La elastografía SWE permite cuantificar esta última característica y puede complementar la evaluación ecográfica convencional.&lt;/p&gt;&lt;p style=&quot;text-align: justify;&quot;&gt;En este paciente, la combinación de hipoecogenicidad difusa, ecotextura heterogénea, engrosamiento del istmo y rigidez aumentada favorece el diagnóstico de tiroiditis crónica autoinmune.&lt;/p&gt;&lt;p style=&quot;text-align: justify;&quot;&gt;La disminución del flujo Doppler no excluye esta posibilidad. La vascularización tiroidea puede variar según la actividad inflamatoria y el estado funcional de la glándula.&lt;/p&gt;&lt;p style=&quot;text-align: justify;&quot;&gt;Es importante distinguir entre una tiroiditis de Hashimoto con aumento de rigidez y una forma específicamente fibrosante. La SWE no demuestra directamente la presencia de fibrosis histológica, y sus resultados deben interpretarse junto con los datos clínicos, analíticos y ecográficos.&lt;/p&gt;&lt;p style=&quot;text-align: justify;&quot;&gt;La evaluación complementaria debería incluir &lt;a data-preview=&quot;&quot; href=&quot;https://www.google.com/search?ved=1t:260882&amp;amp;q=define+TSH+thyroid&amp;amp;bbid=6234332233430215054&amp;amp;bpid=9045040617126848510&quot; target=&quot;_blank&quot;&gt;TSH&lt;/a&gt;, T4 libre y anticuerpos antiperoxidasa tiroidea (anti-TPO); los anticuerpos antitiroglobulina pueden aportar información adicional. La relación entre el aumento de peso y la función tiroidea debe establecerse mediante esta correlación clínica y bioquímica.&lt;/p&gt;&lt;h3 style=&quot;text-align: justify;&quot;&gt;Conclusión ecográfica&lt;/h3&gt;&lt;p style=&quot;text-align: justify;&quot;&gt;Hallazgos tiroideos difusos sugestivos de tiroiditis crónica autoinmune, probablemente enfermedad de Hashimoto, asociados a incremento de la rigidez parenquimatosa en la elastografía SWE.&lt;/p&gt;&lt;p style=&quot;text-align: justify;&quot;&gt;La mediana de 32,80 kPa y la velocidad de 3,28 m/s documentan este incremento de rigidez, sin constituir por sí solas una confirmación de fibrosis avanzada o de una variante fibrosante.&lt;/p&gt;&lt;p style=&quot;text-align: justify;&quot;&gt;Hallazgos abdominales adicionales: esteatosis hepática grado I e hidronefrosis unilateral grado I del riñon izquierdo de etiología no determinada.&lt;/p&gt;&lt;h3 style=&quot;text-align: justify;&quot;&gt;Mensaje clínico&lt;/h3&gt;&lt;p style=&quot;text-align: justify;&quot;&gt;La ecografía convencional, el Doppler color y la elastografía SWE aportan información complementaria. Su integración permite una caracterización más completa de las alteraciones tiroideas difusas y facilita la correlación con la función hormonal y los marcadores de autoinmunidad.&lt;/p&gt;&lt;p style=&quot;text-align: justify;&quot;&gt;La elastografía no sustituye las pruebas de función tiroidea ni la confirmación clínica de la enfermedad, pero puede contribuir a documentar objetivamente los cambios de rigidez y al seguimiento longitudinal cuando se utiliza un protocolo reproducible.&lt;/p&gt;&lt;h2&gt;Valoración crítica del caso&lt;/h2&gt;&lt;p&gt;La evidencia publicada respalda el uso de SWE como herramienta complementaria en la tiroiditis de Hashimoto. Un estudio propuso un punto de corte de 29,45 kPa para identificar la enfermedad, mientras que un &lt;a data-preview=&quot;&quot; href=&quot;https://www.google.com/search?ved=1t:260882&amp;amp;q=metaan%C3%A1lisis+elastograf%C3%ADa+Shear+Wave+Hashimoto&amp;amp;bbid=6234332233430215054&amp;amp;bpid=9045040617126848510&quot; target=&quot;_blank&quot;&gt;metaanálisis publicado en 2026&lt;/a&gt; encontró una rigidez tiroidea significativamente mayor en pacientes con Hashimoto que en controles sanos. No obstante, existe una heterogeneidad importante entre equipos y protocolos, por lo que no sería correcto trasladar directamente ese punto de corte a su Affiniti G70 como criterio definitivo de fibrosis. &lt;/p&gt;&lt;div&gt;&lt;div&gt;&lt;img src=&quot;https://www.google.com/s2/favicons?domain=https://pmc.ncbi.nlm.nih.gov&amp;amp;sz=32&quot; /&gt;&lt;/div&gt;&lt;div&gt;&lt;div&gt;PMC&lt;/div&gt;&lt;div&gt;+1&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;p&gt;&lt;/p&gt;&lt;p&gt;Además, la reducción del flujo Doppler que describe es compatible con algunos patrones de tiroiditis de Hashimoto, aunque no es un hallazgo específico. &lt;/p&gt;&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;/p&gt;&lt;p&gt;&lt;/p&gt;&lt;p&gt;&lt;/p&gt;&lt;div&gt;&lt;div&gt;&lt;div&gt;&lt;a href=&quot;Ecografía y elastografía SWE en un adulto joven con hallazgos sugestivos de tiroiditis de Hashimoto, rigidez tiroidea aumentada, esteatosis hepática e hidronefrosis unilateral.&quot; rel=&quot;nofollow&quot; target=&quot;_blank&quot;&gt;Ecografía y elastografía SWE en un adulto joven con hallazgos sugestivos de tiroiditis de Hashimoto, rigidez tiroidea aumentada, esteatosis hepática e hidronefrosis bilateral.&lt;/a&gt;&lt;img src=&quot;https://www.google.com/s2/favicons?domain=https://pmc.ncbi.nlm.nih.gov&amp;amp;sz=32&quot; /&gt;&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;div&gt;&lt;span&gt;&lt;span&gt;PMC&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;span&gt;+1&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;&lt;/p&gt;&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;&lt;/p&gt;&lt;h2 data-pm-slice=&quot;1 1 []&quot;&gt;Autoimmune Thyroid Disease in a Young Adult: Contributions of Conventional Ultrasound, Color Doppler, and Shear Wave Elastography&lt;/h2&gt;&lt;h3&gt;Introduction&lt;/h3&gt;&lt;p&gt;Weight gain in young adults is a common reason for clinical evaluation and may have multiple causes, including thyroid dysfunction. Ultrasound evaluates thyroid morphology, color Doppler provides information about vascularity, and shear wave elastography (SWE) adds a quantitative estimate of parenchymal stiffness.&lt;/p&gt;&lt;p&gt;This case illustrates the value of integrating these techniques to characterize diffuse thyroid abnormalities and support the evaluation of possible autoimmune thyroid disease.&lt;/p&gt;&lt;h3&gt;Case presentation&lt;/h3&gt;&lt;p&gt;&lt;strong&gt;Patient:&lt;/strong&gt; 20-year-old male referred for abdominal and thyroid ultrasound because of weight gain.&lt;/p&gt;&lt;h3&gt;Ultrasound findings&lt;/h3&gt;&lt;p&gt;&lt;strong&gt;1. Thyroid gland&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;The examination demonstrates:&lt;/p&gt;&lt;ul data-spread=&quot;false&quot;&gt;&lt;li&gt;&lt;p&gt;Thyroid isthmus thickening, measuring approximately 5.9 mm.&lt;/p&gt;&lt;/li&gt;&lt;li&gt;&lt;p&gt;Diffuse parenchymal hypoechogenicity.&lt;/p&gt;&lt;/li&gt;&lt;li&gt;&lt;p&gt;Heterogeneous echotexture.&lt;/p&gt;&lt;/li&gt;&lt;li&gt;&lt;p&gt;Mild contour irregularities involving both lobes.&lt;/p&gt;&lt;/li&gt;&lt;li&gt;&lt;p&gt;Moderately decreased color Doppler vascular signal.&lt;/p&gt;&lt;/li&gt;&lt;/ul&gt;&lt;p&gt;Taken together, these findings suggest chronic thyroiditis, with Hashimoto thyroiditis as the leading diagnostic consideration.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;2. Shear Wave Elastography (SWE)&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;Ten valid acquisitions were obtained from the right thyroid lobe using a Philips Affiniti G70 ultrasound system.&lt;/p&gt;&lt;p&gt;Results:&lt;/p&gt;&lt;ul data-spread=&quot;false&quot;&gt;&lt;li&gt;&lt;p&gt;Median stiffness: &lt;strong&gt;32.80 kPa&lt;/strong&gt;.&lt;/p&gt;&lt;/li&gt;&lt;li&gt;&lt;p&gt;Median shear wave propagation velocity: &lt;strong&gt;3.28 m/s&lt;/strong&gt;.&lt;/p&gt;&lt;/li&gt;&lt;/ul&gt;&lt;p&gt;These measurements indicate increased thyroid tissue stiffness. They are compatible with tissue changes reported in autoimmune thyroiditis; however, they cannot independently establish the histological degree of fibrosis or confirm a specifically fibrosing variant.&lt;/p&gt;&lt;p&gt;Comparisons with published reference values should account for the manufacturer, elastography technique, acquisition protocol, and study population.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;3. Abdominal findings&lt;/strong&gt;&lt;/p&gt;&lt;ul data-spread=&quot;false&quot;&gt;&lt;li&gt;&lt;p&gt;Grade I hepatic steatosis, with preserved liver size.&lt;/p&gt;&lt;/li&gt;&lt;li&gt;&lt;p&gt;Unilateral grade I hydronephrosis left kidney of undetermined etiology.&lt;/p&gt;&lt;/li&gt;&lt;/ul&gt;&lt;p&gt;Unilateral hydronephrosis is a separate finding requiring clinical and urological evaluation to identify its cause and exclude impaired urinary drainage.&lt;/p&gt;&lt;h3&gt;Discussion&lt;/h3&gt;&lt;p&gt;Hashimoto thyroiditis is a chronic autoimmune inflammatory disorder that may produce reduced echogenicity, heterogeneous parenchymal architecture, and increased glandular stiffness. SWE quantifies this mechanical property and may complement conventional ultrasound assessment.&lt;/p&gt;&lt;p&gt;In this patient, diffuse hypoechogenicity, heterogeneous echotexture, isthmus thickening, and increased stiffness support the diagnosis of chronic autoimmune thyroiditis.&lt;/p&gt;&lt;p&gt;Reduced Doppler vascularity does not exclude this diagnosis. Thyroid vascularity may vary according to inflammatory activity and glandular functional status.&lt;/p&gt;&lt;p&gt;A distinction must be made between Hashimoto thyroiditis associated with increased stiffness and a specifically fibrosing form of the disease. SWE does not directly demonstrate histological fibrosis, and its findings should be correlated with clinical, laboratory, and conventional ultrasound data.&lt;/p&gt;&lt;p&gt;Further evaluation should include TSH, free T4, and thyroid peroxidase antibodies (anti-TPO). Thyroglobulin antibodies may provide additional information. The relationship between weight gain and thyroid function should be established through clinical and biochemical correlation.&lt;/p&gt;&lt;h3&gt;Ultrasound conclusion&lt;/h3&gt;&lt;p&gt;Diffuse thyroid abnormalities suggestive of chronic autoimmune thyroiditis, most likely Hashimoto thyroiditis, associated with increased parenchymal stiffness on SWE.&lt;/p&gt;&lt;p&gt;The median stiffness of 32.80 kPa and shear wave velocity of 3.28 m/s document increased stiffness but do not independently confirm advanced fibrosis or a fibrosing variant.&lt;/p&gt;&lt;p&gt;Additional abdominal findings include grade I hepatic steatosis and unilateral grade I hydronephrosis of undetermined etiology.&lt;/p&gt;&lt;h3&gt;Clinical message&lt;/h3&gt;&lt;p&gt;Conventional ultrasound, color Doppler, and SWE provide complementary information. Their integration allows a more comprehensive assessment of diffuse thyroid abnormalities and facilitates correlation with thyroid function and autoimmune markers.&lt;/p&gt;&lt;p&gt;Elastography does not replace thyroid function testing or clinical confirmation of disease, but it may help objectively document changes in tissue stiffness and support longitudinal follow-up when a reproducible protocol is used.&lt;/p&gt;&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;&lt;/p&gt;&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;&lt;/p&gt;&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;&lt;/p&gt;&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;&lt;/p&gt;&lt;p&gt;&lt;br /&gt;&lt;/p&gt;&lt;p&gt;&lt;br /&gt;&lt;/p&gt;&lt;table align=&quot;center&quot;

La ecografía convencional permite detectar alteraciones focales, mientras que el Doppler color y la elastografía Shear Wave (SWE) aportan información complementaria sobre la vascularización y las propiedades mecánicas del tejido.&lt;/p&gt;&lt;p&gt;Presentamos el caso de una paciente de 79 años con varios factores de riesgo cardiovascular y antecedentes de tabaquismo intenso, en quien se identificó una lesión nodular sólida en la región cabeza-cuerpo del páncreas durante una evaluación abdominal rutinaria.&lt;/p&gt;&lt;h3&gt;Presentación del caso&lt;/h3&gt;&lt;p&gt;&lt;strong&gt;Antecedentes clínicos:&lt;/strong&gt; paciente femenina de 79 años, diabética, hipertensa, delgada y gran fumadora, remitida para sonografía abdominal de rutina.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Hallazgos ecográficos:&lt;/strong&gt; en la región correspondiente a la cabeza-cuerpo pancreático se identificó una imagen nodular sólida, ovalada e hipoecogénica, de aproximadamente 2,50 × 1,53 cm.&lt;/p&gt;&lt;p&gt;El hígado no presentaba hepatomegalia ni otras alteraciones ecográficas relevantes descritas en el estudio.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Foto 1.&lt;/strong&gt; Lesión nodular sólida pancreática en escala de grises.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Foto 2.&lt;/strong&gt; Evaluación mediante Doppler color, que demuestra flujo vascular interno mínimo.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Foto 3.&lt;/strong&gt; Aspecto ecográfico del hígado, sin alteraciones relevantes identificadas.&lt;/p&gt;&lt;h3&gt;Evaluación mediante elastografía Shear Wave&lt;/h3&gt;&lt;p&gt;Se realizaron diez adquisiciones elastográficas válidas, con los siguientes resultados:&lt;/p&gt;&lt;ul data-spread=&quot;false&quot;&gt;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Mediana de rigidez:&lt;/strong&gt; 5,61 kPa.&lt;/p&gt;&lt;/li&gt;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Mediana de velocidad de propagación de la onda de corte:&lt;/strong&gt; 1,37 m/s.&lt;/p&gt;&lt;/li&gt;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Número de mediciones válidas:&lt;/strong&gt; 10.&lt;/p&gt;&lt;/li&gt;&lt;/ul&gt;&lt;p&gt;&lt;strong&gt;Foto 4.&lt;/strong&gt; Evaluación elastográfica Shear Wave de la lesión pancreática.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Foto 5.&lt;/strong&gt; Registro de los parámetros cuantitativos de elastografía.&lt;/p&gt;&lt;p&gt;La obtención de diez mediciones válidas permite documentar el resultado de la evaluación realizada. No obstante, el número de adquisiciones, por sí solo, no garantiza la exactitud diagnóstica: también deben considerarse la calidad de la señal, la estabilidad de las mediciones, la profundidad de la lesión, el tamaño y la ubicación de la región de interés (ROI), así como las características técnicas del equipo.&lt;/p&gt;&lt;h3&gt;Discusión&lt;/h3&gt;&lt;p&gt;El hallazgo de una lesión sólida hipoecogénica pancreática de 2,50 cm en una paciente de edad avanzada requiere una caracterización diagnóstica cuidadosa.&lt;/p&gt;&lt;p&gt;La ecografía en escala de grises permite reconocer la lesión y establecer su localización y dimensiones. El Doppler color aporta información sobre la vascularización detectable, aunque un flujo interno mínimo no constituye un criterio suficiente para diferenciar una lesión benigna de una maligna.&lt;/p&gt;&lt;p&gt;La elastografía Shear Wave añade una dimensión cuantitativa al examen, al medir la velocidad de propagación de las ondas de corte y estimar la rigidez tisular. Sin embargo, la rigidez pancreática puede variar según la composición tumoral, la fibrosis, la inflamación, la necrosis y otros factores. Por ello, no existe un valor aislado de SWE que permita confirmar o excluir de manera concluyente una neoplasia pancreática.&lt;/p&gt;&lt;p&gt;En este caso, los valores de 5,61 kPa y 1,37 m/s deben interpretarse como mediciones descriptivas de la lesión, no como evidencia definitiva de benignidad o malignidad. Los umbrales publicados en estudios clínicos tampoco deben trasladarse automáticamente entre plataformas ecográficas diferentes.&lt;/p&gt;&lt;h3&gt;Conducta diagnóstica recomendada&lt;/h3&gt;&lt;p&gt;Por las características de la lesión y el contexto clínico, se recomienda:&lt;/p&gt;&lt;ol data-spread=&quot;false&quot; start=&quot;1&quot;&gt;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Tomografía computarizada multidetector con protocolo pancreático&lt;/strong&gt;, para caracterizar la lesión, evaluar su patrón de realce y estudiar su relación con los vasos y los conductos pancreáticos.&lt;/p&gt;&lt;/li&gt;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Resonancia magnética abdominal con colangiopancreatografía por RM (MRCP)&lt;/strong&gt;, cuando esté indicada para completar la caracterización de la lesión y del sistema ductal.&lt;/p&gt;&lt;/li&gt;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Valoración especializada por gastroenterología y/o cirugía hepatopancreatobiliar&lt;/strong&gt;, según los hallazgos de imagen y la condición clínica.&lt;/p&gt;&lt;/li&gt;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Ecoendoscopia con adquisición de tejido&lt;/strong&gt;, si está indicada, para obtener confirmación citológica o histológica.&lt;/p&gt;&lt;/li&gt;&lt;/ol&gt;&lt;p&gt;La evaluación debe realizarse de forma prioritaria, sin atribuir un diagnóstico histológico definitivo únicamente a los hallazgos ecográficos.&lt;/p&gt;&lt;h3&gt;Conclusión&lt;/h3&gt;&lt;p&gt;Este caso ilustra el valor de la ecografía abdominal como método de detección de lesiones pancreáticas focales y el potencial de la elastografía Shear Wave como herramienta complementaria para su caracterización.&lt;/p&gt;&lt;p&gt;La integración de la morfología, el Doppler color, las mediciones cuantitativas de rigidez y los estudios de imagen seccional constituye un enfoque más sólido que la interpretación aislada de cualquiera de estos parámetros.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Mensaje práctico:&lt;/strong&gt; la elastografía pancreática aporta información cuantitativa, pero no sustituye la caracterización mediante tomografía o resonancia ni la confirmación tisular cuando esta resulta necesaria. La identificación ecográfica oportuna de una lesión sólida puede contribuir a acelerar el proceso diagnóstico y orientar adecuadamente la atención de la paciente.&lt;/p&gt;&lt;div&gt;&lt;hr /&gt;&lt;/div&gt;&lt;h2&gt;ENGLISH VERSION&lt;/h2&gt;&lt;h1&gt;Incidental Solid Pancreatic Lesion in a 79-Year-Old Woman: Contributions of Doppler Ultrasound and Shear Wave Elastography&lt;/h1&gt;&lt;h3&gt;Introduction&lt;/h3&gt;&lt;p&gt;The detection of solid pancreatic lesions during abdominal ultrasound examinations performed for reasons other than suspected pancreatic disease presents a diagnostic challenge. Conventional ultrasound identifies focal abnormalities, while color Doppler and shear wave elastography (SWE) provide complementary information about detectable vascularity and tissue mechanical properties.&lt;/p&gt;&lt;p&gt;We present the case of a 79-year-old woman with several cardiovascular risk factors and a history of heavy smoking in whom a solid nodular lesion was identified in the pancreatic head-body region during a routine abdominal examination.&lt;/p&gt;&lt;h3&gt;Case Presentation&lt;/h3&gt;&lt;p&gt;&lt;strong&gt;Clinical history:&lt;/strong&gt; A 79-year-old woman with diabetes mellitus, hypertension, a slender body habitus, and a history of heavy smoking was referred for routine abdominal ultrasound.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Ultrasound findings:&lt;/strong&gt; A solid, oval, hypoechoic nodular lesion measuring approximately 2.50 × 1.53 cm was identified in the pancreatic head-body region.&lt;/p&gt;&lt;p&gt;The liver showed no hepatomegaly or other relevant sonographic abnormalities described in the examination.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Figure 1.&lt;/strong&gt; Solid pancreatic nodular lesion on grayscale ultrasound.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Figure 2.&lt;/strong&gt; Color Doppler evaluation demonstrating minimal internal vascular flow.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Figure 3.&lt;/strong&gt; Sonographic appearance of the liver, without relevant abnormalities identified.&lt;/p&gt;&lt;h3&gt;Shear Wave Elastography Assessment&lt;/h3&gt;&lt;p&gt;Ten valid elastography acquisitions were obtained, yielding the following results:&lt;/p&gt;&lt;ul data-spread=&quot;false&quot;&gt;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Median stiffness:&lt;/strong&gt; 5.61 kPa.&lt;/p&gt;&lt;/li&gt;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Median shear wave propagation velocity:&lt;/strong&gt; 1.37 m/s.&lt;/p&gt;&lt;/li&gt;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Number of valid measurements:&lt;/strong&gt; 10.&lt;/p&gt;&lt;/li&gt;&lt;/ul&gt;&lt;p&gt;&lt;strong&gt;Figure 4.&lt;/strong&gt; Shear wave elastography assessment of the pancreatic lesion.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Figure 5.&lt;/strong&gt; Recorded quantitative elastography parameters.&lt;/p&gt;&lt;p&gt;Obtaining ten valid acquisitions documents the measurement protocol used. However, the number of acquisitions alone does not guarantee diagnostic accuracy. Signal quality, measurement stability, lesion depth, region-of-interest (ROI) size and location, and the technical characteristics of the ultrasound system must also be considered.&lt;/p&gt;&lt;h3&gt;Discussion&lt;/h3&gt;&lt;p&gt;The identification of a 2.50 cm hypoechoic solid pancreatic lesion in an older patient warrants careful diagnostic characterization.&lt;/p&gt;&lt;p&gt;Grayscale ultrasound identifies the lesion and establishes its location and dimensions. Color Doppler provides information about detectable vascularity, although minimal internal flow is insufficient to distinguish reliably between benign and malignant lesions.&lt;/p&gt;&lt;p&gt;Shear wave elastography adds a quantitative dimension by measuring shear wave propagation velocity and estimating tissue stiffness. Nevertheless, pancreatic stiffness may vary according to tumor composition, fibrosis, inflammation, necrosis, and other factors. Consequently, no single SWE value can conclusively confirm or exclude pancreatic malignancy.&lt;/p&gt;&lt;p&gt;In this case, the values of 5.61 kPa and 1.37 m/s should be interpreted as descriptive measurements of the lesion rather than definitive evidence of benignity or malignancy. Published thresholds should not be automatically transferred between different ultrasound platforms.&lt;/p&gt;&lt;h3&gt;Recommended Diagnostic Approach&lt;/h3&gt;&lt;p&gt;Given the lesion&#39;s characteristics and the patient&#39;s clinical context, the following investigations are recommended:&lt;/p&gt;&lt;ol data-spread=&quot;false&quot; start=&quot;1&quot;&gt;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Multidetector CT with a dedicated pancreatic protocol&lt;/strong&gt;, to characterize the lesion, evaluate its enhancement pattern, and assess its relationship to the vessels and pancreatic ducts.&lt;/p&gt;&lt;/li&gt;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Abdominal MRI with MR cholangiopancreatography (MRCP)&lt;/strong&gt; when indicated to further characterize the lesion and ductal system.&lt;/p&gt;&lt;/li&gt;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Specialist evaluation by gastroenterology and/or hepatopancreatobiliary surgery&lt;/strong&gt;, depending on the imaging findings and clinical condition.&lt;/p&gt;&lt;/li&gt;&lt;li&gt;&lt;p&gt;&lt;strong&gt;Endoscopic ultrasound with tissue acquisition&lt;/strong&gt;, when indicated, to obtain cytological or histological confirmation.&lt;/p&gt;&lt;/li&gt;&lt;/ol&gt;&lt;p&gt;The diagnostic workup should be expedited. A definitive histological diagnosis should not be assigned on the basis of sonographic findings alone.&lt;/p&gt;&lt;h3&gt;Conclusion&lt;/h3&gt;&lt;p&gt;This case illustrates the value of abdominal ultrasound in detecting focal pancreatic lesions and the potential role of shear wave elastography as a complementary characterization tool.&lt;/p&gt;&lt;p&gt;Integrating lesion morphology, color Doppler findings, quantitative stiffness measurements, and cross-sectional imaging provides a more robust diagnostic approach than interpreting any single parameter in isolation.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Practical message:&lt;/strong&gt; pancreatic elastography provides quantitative information, but it does not replace CT or MRI characterization or tissue confirmation when required.

El umbral propuesto en ese estudio fue de 1,77 m/s. &lt;/p&gt;&lt;div&gt;&lt;div&gt;&lt;img src=&quot;https://www.google.com/s2/favicons?domain=https://pubmed.ncbi.nlm.nih.gov&amp;amp;sz=32&quot; /&gt;&lt;/div&gt;&lt;div&gt;PubMed&lt;/div&gt;&lt;/div&gt;&lt;p&gt;&lt;/p&gt;&lt;p&gt;La velocidad de 1,37 m/s de esta paciente se encuentra próxima a la media benigna de esa investigación. Sin embargo, no es válido concluir que la lesión es benigna por esa coincidencia, porque se desconocen aquí la comparabilidad exacta del equipo, el protocolo de adquisición y la población de referencia. Además, la evidencia actual no respalda la SWE como prueba independiente para descartar una neoplasia pancreática. &lt;/p&gt;&lt;div&gt;&lt;div&gt;&lt;img src=&quot;https://www.google.com/s2/favicons?domain=https://pmc.ncbi.nlm.nih.gov&amp;amp;sz=32&quot; /&gt;&lt;/div&gt;&lt;div&gt;&lt;div&gt;PMC&lt;/div&gt;&lt;div&gt;+1&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;p&gt;&lt;/p&gt;&lt;p&gt;La aportación más valiosa de este caso es documentar una lesión pancreática focal mediante tres modalidades complementarias —escala de grises, Doppler y SWE cuantitativa— y mostrar por qué sus resultados deben integrarse con la imagen seccional y, cuando corresponda, con el estudio histológico.&lt;/p&gt;&lt;/div&gt;&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;&lt;h1 data-pm-slice=&quot;1 1 []&quot;&gt;Incidental Solid Pancreatic Lesion in a 79-Year-Old Woman: Contributions of Doppler Ultrasound and Shear Wave Elastography&lt;/h1&gt;&lt;h3&gt;Introduction&lt;/h3&gt;&lt;p&gt;The detection of solid pancreatic lesions during abdominal ultrasound examinations performed for reasons other than suspected pancreatic disease presents a diagnostic challenge.

Systematic accumulation of these data may help improve our understanding of the elastographic behavior of thyroid nodules evaluated with the &lt;strong&gt;Philips Affiniti 70 G&lt;/strong&gt; and contribute to greater clinical experience with this technology.&lt;/p&gt;&lt;p&gt;&lt;br /&gt;&lt;/p&gt;&lt;table align=&quot;center&quot;

In both cases, 10 valid acquisitions were obtained from each kidney, with the regions of interest placed within the renal cortex while avoiding blood vessels and other structures that could potentially alter the measurements.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Evaluation of both kidneys is particularly useful because it allows the identification of possible &lt;strong&gt;asymmetries in cortical stiffness&lt;/strong&gt;.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;In the first case, the difference between &lt;strong&gt;4.25 kPa in the right kidney and 7.44 kPa in the left kidney&lt;/strong&gt; represents the most relevant quantitative finding. This difference was not accompanied by an evident alteration in corticomedullary differentiation on conventional ultrasound.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;In the second case, the measurements were similar between both kidneys, with values of &lt;strong&gt;3.75 and 3.91 kPa&lt;/strong&gt;, respectively.&lt;/p&gt;&lt;div contenteditable=&quot;false&quot;&gt;&lt;hr /&gt;&lt;/div&gt;&lt;h1&gt;What Can Renal SWE Add?&lt;/h1&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;The value of renal elastography does not lie simply in obtaining a number expressed in kPa or m/s. Its potential value lies in providing a &lt;strong&gt;quantitative measurement that complements the morphological information obtained from conventional ultrasound&lt;/strong&gt;.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;In patients with chronic diseases such as type 2 diabetes mellitus, an approach combining:&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;strong&gt;Conventional ultrasound + Doppler + Shear Wave Elastography&lt;/strong&gt;&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;may provide a more comprehensive characterization of renal status.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;SWE may be particularly useful as a follow-up tool, allowing successive measurements obtained under similar technical conditions to be compared and potentially documenting changes in cortical stiffness over time.&lt;/p&gt;&lt;h3&gt;Conclusion&lt;/h3&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;These two cases demonstrate how Renal Shear Wave Elastography may provide additional quantitative information in patients with type 2 diabetes mellitus, even when conventional ultrasound demonstrates preserved corticomedullary differentiation.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;In the first case, the difference in stiffness between the two kidneys revealed an asymmetric quantitative pattern, with a higher SWE value in the left renal cortex. In the second case, the measurements were similar bilaterally and were interpreted as corresponding to a preserved renal cortex.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;strong&gt;Renal SWE should not be considered in isolation as a diagnostic test for diabetic nephropathy.&lt;/strong&gt; Its interpretation should be integrated with the patient&#39;s clinical history, renal function, albuminuria/proteinuria, Doppler findings, morphological characteristics, and clinical follow-up.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Its main potential lies in providing a &lt;strong&gt;quantitative, reproducible, and noninvasive tool to complement the assessment and follow-up of structural changes in the renal parenchyma&lt;/strong&gt;.&lt;/p&gt;&lt;p&gt;These cases highlight the potential value of SWE in chronic diseases capable of producing structural renal changes, particularly type 2 diabetes mellitus.&lt;/p&gt;&lt;/div&gt;&lt;div align=&quot;left&quot;

La ecografía convencional y el Doppler permiten valorar la morfología del injerto, su vascularización y la presencia de complicaciones estructurales.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;En los últimos años, la &lt;strong&gt;Elastografía Shear Wave (SWE)&lt;/strong&gt; ha incorporado un parámetro cuantitativo adicional: la medición de la rigidez del parénquima renal.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Sin embargo, la interpretación de la SWE en el riñón trasplantado requiere especial prudencia. Los valores obtenidos pueden estar condicionados por múltiples factores clínicos y técnicos, y &lt;strong&gt;una medición aislada no debe utilizarse por sí sola para diagnosticar fibrosis, rechazo o

aproximadamente &lt;strong&gt;20–22 leucocitos por campo&lt;/strong&gt;, sin células renales.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Estos resultados son compatibles con un importante proceso infeccioso sistémico, asociado a infección urinaria y gastrointestinal.&lt;/p&gt;&lt;div contenteditable=&quot;false&quot;&gt;&lt;hr /&gt;&lt;/div&gt;&lt;h1&gt;Evaluación

class=&quot;isSelectedEnd&quot;&gt;Este aspecto es particularmente importante porque indica que, desde el punto de vista morfológico y hemodinámico convencional, &lt;strong&gt;el injerto no presentaba alteraciones sonográficas evidentes&lt;/strong&gt;.&lt;/p&gt;&lt;div contenteditable=&quot;false&quot;&gt;&lt;hr /&gt;&lt;/div&gt;&lt;h1&gt;Elastografía Shear Wave&lt;/h1&gt;&lt;p

m/s&lt;/strong&gt;&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;El valor obtenido puede considerarse &lt;strong&gt;relativamente bajo dentro del espectro de valores publicados para la corteza de riñones trasplantados&lt;/strong&gt;.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;No obstante, este resultado debe interpretarse con cautela.&lt;/p&gt;&lt;div contenteditable=&quot;false&quot;&gt;&lt;hr /&gt;&lt;/div&gt;&lt;h1&gt;¿Qué significa una SWE de 12.45 kPa?&lt;/h1&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Uno de los principales errores en la interpretación de la elastografía renal es asumir que:&lt;/p&gt;&lt;blockquote&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&quot;Mayor rigidez = enfermedad&quot;&lt;br /&gt;&quot;Menor rigidez = riñón sano&quot;.&lt;/p&gt;&lt;/blockquote&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;La realidad es considerablemente más compleja.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;La rigidez cortical renal puede estar influenciada por:&lt;/p&gt;&lt;ul data-spread=&quot;false&quot;&gt;&lt;li&gt;Fibrosis intersticial.&lt;/li&gt;&lt;li&gt;Alteraciones hemodinámicas.&lt;/li&gt;&lt;li&gt;Perfusión renal.&lt;/li&gt;&lt;li&gt;Presión intrarrenal.&lt;/li&gt;&lt;li&gt;Estado de hidratación.&lt;/li&gt;&lt;li&gt;Inflamación.&lt;/li&gt;&lt;li&gt;Edema.&lt;/li&gt;&lt;li&gt;Presión ejercida por el transductor.&lt;/li&gt;&lt;li&gt;Profundidad del ROI.&lt;/li&gt;&lt;li&gt;Tamaño y localización del ROI.&lt;/li&gt;&lt;li&gt;Características del equipo.&lt;/li&gt;&lt;li&gt;Transductor utilizado.&lt;/li&gt;&lt;li&gt;Técnica de adquisición.&lt;/li&gt;&lt;li&gt;Edad del paciente.&lt;/li&gt;&lt;li&gt;Condiciones clínicas agudas.&lt;/li&gt;&lt;/ul&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Por esta razón, &lt;strong&gt;no debe establecerse un diagnóstico de rechazo o fibrosis únicamente a partir de un valor de SWE&lt;/strong&gt;.&lt;/p&gt;&lt;div contenteditable=&quot;false&quot;&gt;&lt;hr /&gt;&lt;/div&gt;&lt;h1&gt;Un aspecto particularmente importante en este caso&lt;/h1&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;El paciente se encontraba cursando un &lt;strong&gt;proceso infeccioso agudo&lt;/strong&gt;, con fiebre elevada, leucocitosis importante y diarrea profusa.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;La diarrea intensa también plantea la posibilidad de alteraciones del estado de hidratación y del volumen circulante.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Por ello, la medición de &lt;strong&gt;12.45 kPa debe considerarse dentro de un contexto fisiopatológico dinámico&lt;/strong&gt;.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Es decir:&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;strong&gt;la SWE obtenida durante una enfermedad aguda representa el estado del injerto en ese momento específico y no necesariamente su comportamiento basal.&lt;/strong&gt;&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Este concepto es fundamental.&lt;/p&gt;&lt;div contenteditable=&quot;false&quot;&gt;&lt;hr /&gt;&lt;/div&gt;&lt;h1&gt;¿Debemos considerar 12.45 kPa como un valor patológico?&lt;/h1&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;No necesariamente.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;La medición puede describirse como:&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;strong&gt;&quot;Rigidez cortical relativamente baja&quot;&lt;/strong&gt;&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;pero no debería transformarse automáticamente en:&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;strong&gt;&quot;Ausencia de fibrosis&quot;&lt;/strong&gt;,&lt;br /&gt;&lt;strong&gt;&quot;Buena función renal&quot;&lt;/strong&gt; o&lt;br /&gt;&lt;strong&gt;&quot;Ausencia de rechazo&quot;.&lt;/strong&gt;&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;La función del injerto debe correlacionarse con:&lt;/p&gt;&lt;ul data-spread=&quot;false&quot;&gt;&lt;li&gt;Creatinina.&lt;/li&gt;&lt;li&gt;Tasa de filtración glomerular estimada.&lt;/li&gt;&lt;li&gt;Proteinuria.&lt;/li&gt;&lt;li&gt;Sedimento urinario.&lt;/li&gt;&lt;li&gt;Evolución clínica.&lt;/li&gt;&lt;li&gt;Estudios Doppler.&lt;/li&gt;&lt;li&gt;Antecedentes de rechazo.&lt;/li&gt;&lt;li&gt;Tiempo desde el trasplante.&lt;/li&gt;&lt;li&gt;Mediciones elastográficas previas.&lt;/li&gt;&lt;/ul&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;La SWE es, por tanto, &lt;strong&gt;una herramienta complementaria y no un sustituto de la evaluación nefrológica ni de la biopsia cuando esta esté clínicamente indicada.&lt;/strong&gt;&lt;/p&gt;&lt;div contenteditable=&quot;false&quot;&gt;&lt;hr /&gt;&lt;/div&gt;&lt;h1&gt;La importancia del seguimiento elastográfico&lt;/h1&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Aquí considero que existe uno de los mayores potenciales clínicos de la SWE en el paciente trasplantado.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Una medición aislada tiene un valor limitado.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;En cambio, &lt;strong&gt;una serie de mediciones realizadas bajo condiciones técnicas y clínicas comparables puede proporcionar información mucho más útil.&lt;/strong&gt;&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Por ejemplo:&lt;/p&gt;&lt;h3&gt;Primera evaluación&lt;/h3&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Paciente durante un episodio infeccioso:&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;strong&gt;12.45 kPa&lt;/strong&gt;&lt;/p&gt;&lt;h3&gt;Segunda evaluación&lt;/h3&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Una vez resuelto el proceso infeccioso y recuperado el estado clínico:&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;strong&gt;nueva medición SWE&lt;/strong&gt;&lt;/p&gt;&lt;h3&gt;Tercera evaluación&lt;/h3&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Durante el seguimiento habitual del trasplante:&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;strong&gt;nueva medición SWE&lt;/strong&gt;&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;La comparación longitudinal podría permitir identificar:&lt;/p&gt;&lt;ul data-spread=&quot;false&quot;&gt;&lt;li&gt;Estabilidad del comportamiento elastográfico.&lt;/li&gt;&lt;li&gt;Incrementos progresivos de la rigidez.&lt;/li&gt;&lt;li&gt;Descensos significativos.&lt;/li&gt;&lt;li&gt;Cambios asociados a deterioro de la función renal.&lt;/li&gt;&lt;li&gt;Cambios relacionados temporalmente con episodios inflamatorios o infecciosos.&lt;/li&gt;&lt;/ul&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Este enfoque es potencialmente mucho más valioso que intentar interpretar cada número de manera aislada.&lt;/p&gt;&lt;div contenteditable=&quot;false&quot;&gt;&lt;hr /&gt;&lt;/div&gt;&lt;h1&gt;Propuesta de seguimiento&lt;/h1&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;En pacientes con trasplante renal que presenten procesos infecciosos, alteraciones de la función renal, proteinuria, sospecha clínica de disfunción del injerto o cambios en los estudios convencionales, puede ser razonable considerar una &lt;strong&gt;SWE de seguimiento después de la resolución del proceso agudo&lt;/strong&gt;.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;En un caso como el presentado, una estrategia práctica sería:&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;strong&gt;SWE durante el episodio agudo → resolución de la infección → nueva SWE de control → comparación con mediciones previas y función renal.&lt;/strong&gt;&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;La comparación debe realizarse procurando mantener:&lt;/p&gt;&lt;ul data-spread=&quot;false&quot;&gt;&lt;li&gt;El mismo equipo.&lt;/li&gt;&lt;li&gt;El mismo transductor.&lt;/li&gt;&lt;li&gt;La misma región cortical.&lt;/li&gt;&lt;li&gt;Una técnica de adquisición reproducible.&lt;/li&gt;&lt;li&gt;Condiciones similares de preparación.&lt;/li&gt;&lt;li&gt;Evitar vasos y estructuras sinusales.&lt;/li&gt;&lt;li&gt;ROI adecuado.&lt;/li&gt;&lt;li&gt;Número suficiente de mediciones válidas.&lt;/li&gt;&lt;/ul&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;La finalidad no sería establecer un diagnóstico exclusivamente mediante SWE, sino &lt;strong&gt;incorporar una variable cuantitativa adicional al seguimiento del injerto renal.&lt;/strong&gt;&lt;/p&gt;&lt;div contenteditable=&quot;false&quot;&gt;&lt;hr /&gt;&lt;/div&gt;&lt;h1&gt;Un concepto que merece especial atención: el valor de referencia individual&lt;/h1&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;En el paciente trasplantado, probablemente sea más útil conocer &lt;strong&gt;la evolución individual de la rigidez

class=&quot;isSelectedEnd&quot;&gt;En el paciente trasplantado, donde preservar la función del injerto constituye un objetivo fundamental, disponer de una técnica no invasiva, repetible y cuantitativa que complemente la ecografía convencional, el Doppler y los parámetros bioquímicos puede representar una importante oportunidad para mejorar el seguimiento.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;La interpretación responsable de la SWE exige, sin embargo, reconocer sus limitaciones y evitar convertir un valor elastográfico aislado en un diagnóstico

Conventional B-mode imaging and Doppler ultrasound provide valuable information regarding graft morphology, vascular perfusion and structural complications.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;strong&gt;Shear Wave Elastography (SWE)&lt;/strong&gt; adds a quantitative assessment of renal cortical stiffness.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;However, SWE findings in renal transplantation require careful interpretation. Graft stiffness is influenced by multiple technical and biological factors, and &lt;strong&gt;an isolated SWE measurement should not be used independently to diagnose fibrosis, rejection, or graft

class=&quot;isSelectedEnd&quot;&gt;This patient was undergoing a significant acute infectious process, with high fever, marked leukocytosis and profuse diarrhea.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Severe diarrhea may also produce changes in hydration and circulatory volume.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Therefore, the &lt;strong&gt;12.45 kPa measurement represents the mechanical characteristics of the graft under acute clinical conditions&lt;/strong&gt; and may not necessarily represent the patient&#39;s baseline elastographic status.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;This distinction is particularly important when interpreting renal transplant SWE.&lt;/p&gt;&lt;div contenteditable=&quot;false&quot;&gt;&lt;hr /&gt;&lt;/div&gt;&lt;h1&gt;Is 12.45 kPa pathological?&lt;/h1&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Not necessarily.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;The finding can appropriately be described as:&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;strong&gt;&quot;Relatively low cortical stiffness.&quot;&lt;/strong&gt;&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;However, it should not automatically be interpreted as:&lt;/p&gt;&lt;p

may be &lt;strong&gt;longitudinal monitoring rather than interpretation of a single measurement.&lt;/strong&gt;&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;For example:&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;strong&gt;Acute infection:&lt;/strong&gt;&lt;br /&gt;12.45 kPa&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;strong&gt;After resolution of

conditions&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;The evolution of these measurements may provide additional information regarding the stability or change in graft cortical mechanical

behavior.&lt;/li&gt;&lt;li&gt;Progressive increases in cortical stiffness.&lt;/li&gt;&lt;li&gt;Significant changes from an established baseline.&lt;/li&gt;&lt;li&gt;Changes occurring in association

/&gt;&lt;/div&gt;&lt;h1&gt;Establishing an individual elastographic baseline&lt;/h1&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;In transplanted kidneys, an individual baseline may ultimately prove more useful than relying exclusively on a universal cutoff value.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;For example:&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;strong&gt;12 → 14

kPa&lt;/strong&gt;&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Even when individual values overlap with published ranges, the &lt;strong&gt;trend over time&lt;/strong&gt; may provide clinically relevant information.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Therefore, establishing a reliable baseline SWE measurement after stabilization of the transplant may be particularly valuable for future comparison.&lt;/p&gt;&lt;div contenteditable=&quot;false&quot;&gt;&lt;hr /&gt;&lt;/div&gt;&lt;h1&gt;Suggested follow-up strategy&lt;/h1&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;For renal

graft morphology,&lt;/li&gt;&lt;/ul&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;a &lt;strong&gt;follow-up SWE after resolution of the acute clinical condition&lt;/strong&gt; may be considered.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;A practical approach in cases such as this would be:&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;strong&gt;SWE during the acute episode → clinical recovery → repeat SWE → comparison with baseline and renal function.&lt;/strong&gt;&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;For meaningful comparison, the follow-up examination should preferably use:&lt;/p&gt;&lt;ul data-spread=&quot;false&quot;&gt;&lt;li&gt;The same ultrasound system.&lt;/li&gt;&lt;li&gt;The same transducer.&lt;/li&gt;&lt;li&gt;Comparable

La ausencia de la glándula modifica la anatomía habitual y obliga al explorador a prestar especial atención al lecho quirúrgico, al tejido residual y a las estructuras cervicales adyacentes.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;La identificación de una imagen nodular en el lecho tiroideo no debe interpretarse automáticamente como recurrencia tumoral. Es necesario integrar sus características morfológicas, vascularización, comportamiento elastográfico, antecedentes quirúrgicos y evolución temporal.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Presentamos el caso de una paciente femenina de 64 años, asintomática, con antecedente de tiroidectomía realizada varios años antes, en quien se identificó una lesión nodular en el lecho tiroideo izquierdo.&lt;/p&gt;&lt;div contenteditable=&quot;false&quot;&gt;&lt;hr /&gt;&lt;/div&gt;&lt;h2&gt;Presentación del caso&lt;/h2&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Paciente femenina de &lt;strong&gt;64 años de edad&lt;/strong&gt;, con antecedente de &lt;strong&gt;tiroidectomía realizada varios años atrás&lt;/strong&gt;, quien acude para control sonográfico rutinario.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Al momento del estudio se encuentra asintomática.

10 valid measurements, with a median of &lt;strong&gt;22.10 kPa&lt;/strong&gt; and shear wave velocity of &lt;strong&gt;2.71 m/s&lt;/strong&gt;, consistent with increased stiffness of the evaluated tissue.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;The finding should be interpreted in conjunction with the patient&#39;s surgical history, particularly the original indication for thyroidectomy and the previous histopathological diagnosis.&lt;/p&gt;&lt;div contenteditable=&quot;false&quot;&gt;&lt;hr /&gt;&lt;/div&gt;&lt;h2&gt;Final Considerations&lt;/h2&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;This case demonstrates one of the major strengths of ultrasound: the ability to combine different imaging modalities during a single real-time examination.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Conventional grayscale ultrasound provides morphological information; Doppler evaluates vascular behavior, while elastography provides additional information regarding the mechanical properties of the tissue.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;However, &lt;strong&gt;none of these parameters should be interpreted in isolation&lt;/strong&gt;.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;In post-thyroidectomy patients, fibrosis and postsurgical changes represent an important potential source of false-positive findings, particularly with elastography. Therefore, an elevated SWE value should be considered a &lt;strong&gt;complementary finding&lt;/strong&gt;, rather than a definitive diagnostic criterion.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;The true value of elastography lies in integrating it with meticulous anatomical assessment, Doppler evaluation, previous examinations, clinical history, and, when appropriate, biochemical and histopathological information.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Cases such as this also demonstrate the important role of ultrasound as a dynamic, high-resolution method for monitoring patients after thyroid surgery. It allows the detection of small changes within the surgical bed and provides additional information that may help guide further clinical management.&lt;/p&gt;&lt;h3&gt;Conclusion&lt;/h3&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;strong&gt;Solid hypoechoic nodule measuring 1.21 × 0.81 cm within the left thyroid bed, demonstrating internal vascularity on color Doppler and increased stiffness on SWE (22.10 kPa; 2.71 m/s).&lt;/strong&gt;&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;strong&gt;The clinical significance of this finding depends primarily on the indication for the original thyroidectomy, its temporal behavior, and the presence or absence of additional suspicious sonographic features.&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;Correlation with previous examinations and systematic evaluation of the cervical lymph node chains are essential for appropriate risk assessment.&lt;/p&gt;&lt;/div&gt;&lt;div class=&quot;separator&quot;

patient with diverticular disease without sonographic evidence of active inflammation had a median stiffness of &lt;strong&gt;22.95 KPa&lt;/strong&gt;, whereas the patient with findings suggestive of diverticulitis had a median of &lt;strong&gt;20.30 KPa&lt;/strong&gt;.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;This raises an interesting hypothesis:&lt;/p&gt;&lt;blockquote&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;strong&gt;SWE-measured stiffness may reflect chronic structural changes of the diverticular wall more strongly than acute inflammatory activity alone.&lt;/strong&gt;&lt;/p&gt;&lt;/blockquote&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;This hypothesis cannot be established from two patients, but it represents an interesting potential area for

valuable tool for evaluating colonic diverticular disease when a systematic protocol integrates &lt;strong&gt;gray-scale imaging, wall-thickness measurement, Color Doppler, and Shear Wave Elastography&lt;/strong&gt;.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;In these two cases, elevated stiffness values of &lt;strong&gt;22.95 KPa&lt;/strong&gt; and &lt;strong&gt;20.30 KPa&lt;/strong&gt;, respectively, were obtained. However, these values did not show a direct relationship with the presence of sonographic signs of acute inflammation.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;The second case demonstrated an additional morphological finding of greater diagnostic relevance: &lt;strong&gt;focal thickening of the diverticular wall measuring up to 5.0 mm&lt;/strong&gt;, associated with symptoms compatible with diverticulitis. The absence of collections, abscesses, free fluid, and other signs of complications allowed the process to be considered &lt;strong&gt;uncomplicated from a sonographic standpoint&lt;/strong&gt;.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;These findings suggest that &lt;strong&gt;SWE should currently be considered a complementary parameter&lt;/strong&gt;, and its actual role in differentiating chronic diverticular disease from acute diverticulitis requires evaluation in larger patient populations.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Systematic accumulation of cases and correlation between morphological, Doppler, and elastographic parameters may help determine whether SWE can become a &lt;strong&gt;quantitative biomarker of structural changes or inflammatory activity in the diverticular wall&lt;/strong&gt;.&lt;/p&gt;&lt;div contenteditable=&quot;false&quot;&gt;&lt;hr /&gt;&lt;/div&gt;&lt;h1&gt;Final Message&lt;/h1&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;The principal strength of ultrasound in the evaluation of diverticular disease does not lie in a single parameter, but rather in the &lt;strong&gt;integration of multiple variables obtained during the same examination&lt;/strong&gt;.&lt;/p&gt;&lt;p&gt;The combination of morphology, wall thickness, Color Doppler, and SWE opens an interesting possibility: transforming the traditional descriptive assessment of diverticula into a &lt;strong&gt;morphological and quantitative evaluation&lt;/strong&gt;, potentially useful for monitoring the evolution of these patients.&lt;/p&gt;&lt;p&gt;&lt;br /&gt;&lt;/p&gt;&lt;table align=&quot;center&quot;

&lt;p data-end=&quot;519&quot; data-start=&quot;268&quot;&gt;An 83-year-old man presented after sustaining a slip-and-fall accident at home. He complained of severe left shoulder pain associated with marked limitation of shoulder mobility. Mild superficial skin abrasions were observed over the injured shoulder.&lt;/p&gt;

A focal heterogeneous lesion was identified within the left supraspinatus tendon, characterized by a hypoechoic-to-anechoic area with loss of the normal tendon echotexture and disruption of the fibrillar pattern, consistent with a partial-thickness tendon tear.&lt;/p&gt;
&lt;p data-end=&quot;1045&quot; data-start=&quot;901&quot;&gt;No additional sonographically detectable abnormalities were identified in the remaining components of the rotator cuff or adjacent soft tissues.&lt;/p&gt;

&lt;p data-end=&quot;1227&quot; data-start=&quot;1075&quot;&gt;Color Doppler imaging demonstrated increased vascularity (reactive hyperemia) within the injured tendon, compatible with an acute inflammatory response.&lt;/p&gt;

&lt;p data-end=&quot;1330&quot; data-start=&quot;1273&quot;&gt;Ten valid SWE measurements were obtained from the lesion.&lt;/p&gt;

&lt;p data-end=&quot;2584&quot; data-start=&quot;2382&quot;&gt;Las áreas infartadas mostraron un incremento de rigidez respecto al parénquima esplénico normal descrito en la literatura, hallazgo compatible con organización fibrótica secundaria al proceso isquémico.&lt;/p&gt;

&lt;h1 data-end=&quot;2602&quot; data-section-id=&quot;1e35549&quot; data-start=&quot;2591&quot;&gt;Discusión&lt;/h1&gt;
&lt;p data-end=&quot;2764&quot; data-start=&quot;2604&quot;&gt;La enfermedad de células falciformes produce episodios repetidos de oclusión microvascular que afectan especialmente al bazo durante la infancia y adolescencia.&lt;/p&gt;
&lt;p data-end=&quot;2994&quot; data-start=&quot;2766&quot;&gt;La isquemia conduce inicialmente a necrosis del tejido esplénico y posteriormente a fenómenos de reparación con fibrosis focal. En fases avanzadas, los infartos repetitivos ocasionan la denominada &lt;strong data-end=&quot;2993&quot; data-start=&quot;2963&quot;&gt;&lt;a data-preview=&quot;&quot; href=&quot;https://www.google.com/search?ved=1t:260882&amp;amp;q=define+autosplenectom%C3%ADa+funcional&amp;amp;bbid=6234332233430215054&amp;amp;bpid=7199563410080759174&quot; target=&quot;_blank&quot;&gt;autosplenectomía funcional&lt;/a&gt;&lt;/strong&gt;.&lt;/p&gt;
&lt;p data-end=&quot;3214&quot; data-start=&quot;2996&quot;&gt;La ecografía constituye el método inicial de elección para detectar estas lesiones, mientras que la elastografía Shear Wave permite aportar información adicional acerca de las propiedades mecánicas del tejido afectado.&lt;/p&gt;
&lt;p data-end=&quot;3406&quot; data-start=&quot;3216&quot;&gt;En este caso, el valor obtenido de &lt;strong data-end=&quot;3263&quot; data-start=&quot;3251&quot;&gt;9.75 kPa&lt;/strong&gt; sugiere un aumento significativo de la rigidez del tejido infartado, probablemente relacionado con fibrosis reparativa relativamente reciente.&lt;/p&gt;
&lt;p data-end=&quot;3741&quot; data-start=&quot;3408&quot;&gt;Aunque actualmente existen publicaciones sobre elastografía del bazo en hipertensión portal, fibrosis hepática, enfermedades hematológicas y procesos infiltrativos, la información disponible sobre &lt;strong data-end=&quot;3652&quot; data-start=&quot;3605&quot;&gt;elastografía de infartos esplénicos focales&lt;/strong&gt; es extremadamente limitada, especialmente utilizando tecnología Shear Wave cuantitativa.&lt;/p&gt;

&lt;h1 data-end=&quot;3922&quot; data-section-id=&quot;fsbaih&quot; data-start=&quot;3910&quot;&gt;Conclusión&lt;/h1&gt;
&lt;p data-end=&quot;4071&quot; data-start=&quot;3924&quot;&gt;La ecografía permitió identificar múltiples infartos esplénicos en una paciente con anemia falciforme homocigótica durante una crisis vasooclusiva.&lt;/p&gt;
&lt;p data-end=&quot;4249&quot; data-start=&quot;4073&quot;&gt;La elastografía Shear Wave demostró un incremento de la rigidez de la lesión de mayor tamaño (&lt;strong data-end=&quot;4189&quot; data-start=&quot;4167&quot;&gt;9.75 kPa; 1.78 m/s&lt;/strong&gt;), compatible con cambios fibróticos secundarios al infarto.&lt;/p&gt;
&lt;p data-end=&quot;4566&quot; data-start=&quot;4251&quot;&gt;La incorporación rutinaria de la elastografía podría contribuir a caracterizar la evolución temporal de los infartos esplénicos y diferenciar lesiones agudas de áreas con fibrosis organizada, aunque serán necesarios estudios con mayor número de pacientes para establecer valores de referencia y su utilidad clínica.&lt;/p&gt;

&lt;p data-end=&quot;1825&quot; data-start=&quot;1643&quot;&gt;The infarcted area demonstrated increased stiffness compared with normal splenic parenchyma reported in the literature, consistent with reparative fibrosis following ischemic injury.&lt;/p&gt;

&lt;h1 data-end=&quot;1844&quot; data-section-id=&quot;j601ae&quot; data-start=&quot;1832&quot;&gt;Discussion&lt;/h1&gt;
&lt;p data-end=&quot;1989&quot; data-start=&quot;1846&quot;&gt;Sickle cell disease produces recurrent episodes of microvascular occlusion, particularly affecting the spleen during childhood and adolescence.&lt;/p&gt;
&lt;p data-end=&quot;2198&quot; data-start=&quot;1991&quot;&gt;Ischemia initially results in tissue necrosis followed by reparative fibrosis. Recurrent infarctions eventually lead to progressive loss of splenic function and, in many patients, functional autosplenectomy.&lt;/p&gt;
&lt;p data-end=&quot;2431&quot; data-start=&quot;2200&quot;&gt;Ultrasound is the imaging modality of choice for the initial detection of splenic infarctions, whereas Shear Wave Elastography provides additional quantitative information regarding the mechanical properties of the affected tissue.&lt;/p&gt;
&lt;p data-end=&quot;2601&quot; data-start=&quot;2433&quot;&gt;In the present case, the measured stiffness of &lt;strong data-end=&quot;2492&quot; data-start=&quot;2480&quot;&gt;9.75 kPa&lt;/strong&gt; suggests a significant increase in tissue rigidity, likely reflecting relatively recent reparative fibrosis.&lt;/p&gt;
&lt;p data-end=&quot;2882&quot; data-start=&quot;2603&quot;&gt;Although splenic elastography has been investigated in portal hypertension, chronic liver disease, hematologic disorders, and infiltrative diseases, published data regarding &lt;strong data-end=&quot;2881&quot; data-start=&quot;2777&quot;&gt;focal splenic infarctions evaluated by quantitative Shear Wave Elastography remain extremely limited&lt;/strong&gt;.&lt;/p&gt;
&lt;p data-end=&quot;3042&quot; data-start=&quot;2884&quot;&gt;This case provides preliminary evidence regarding the elastographic characteristics of splenic infarction and may contribute to future research in this field.&lt;/p&gt;

&lt;h1 data-end=&quot;3061&quot; data-section-id=&quot;fsb6xx&quot; data-start=&quot;3049&quot;&gt;Conclusion&lt;/h1&gt;
&lt;p data-end=&quot;3194&quot; data-start=&quot;3063&quot;&gt;Ultrasound identified multiple splenic infarctions in a patient with homozygous sickle cell disease during a vaso-occlusive crisis.&lt;/p&gt;
&lt;p data-end=&quot;3368&quot; data-start=&quot;3196&quot;&gt;Shear Wave Elastography demonstrated increased stiffness within the largest infarct (&lt;strong data-end=&quot;3303&quot; data-start=&quot;3281&quot;&gt;9.75 kPa; 1.78 m/s&lt;/strong&gt;), consistent with reparative fibrosis following ischemic injury.&lt;/p&gt;
&lt;p data-end=&quot;3726&quot; data-start=&quot;3370&quot;&gt;Routine incorporation of SWE may improve the characterization of splenic infarctions, assist in differentiating acute from chronic lesions, and potentially allow noninvasive monitoring of tissue remodeling. Further studies involving larger patient populations are required to establish reference values and determine the clinical utility of this technique.&lt;/p&gt;

&lt;p data-end=&quot;716&quot; data-start=&quot;553&quot;&gt;La exploración con transductor lineal de alta frecuencia demuestra una lesión nodular sólida localizada en la &lt;strong data-end=&quot;715&quot; data-start=&quot;663&quot;&gt;posición radial de las 6:00 de la mama izquierda&lt;/strong&gt;.&lt;/p&gt;

&lt;p data-end=&quot;1412&quot; data-start=&quot;1278&quot;&gt;El estudio Doppler color evidencia &lt;strong data-end=&quot;1359&quot; data-start=&quot;1313&quot;&gt;&lt;a data-preview=&quot;&quot; href=&quot;https://www.google.com/search?ved=1t:260882&amp;amp;q=define+vascularizaci%C3%B3n+intranodular+significativa&amp;amp;bbid=6234332233430215054&amp;amp;bpid=4632136742399698101&quot; target=&quot;_blank&quot;&gt;vascularización intranodular significativa&lt;/a&gt;&lt;/strong&gt;, sin observar vasos de trayecto irregular o caótico.&lt;/p&gt;

&lt;p data-end=&quot;1610&quot; data-start=&quot;1473&quot;&gt;Se realizó elastografía cuantitativa mediante técnica &lt;strong data-end=&quot;1541&quot; data-start=&quot;1527&quot;&gt;Shear Wave&lt;/strong&gt;, obteniéndose diez (10) mediciones independientes dentro del nódulo.&lt;/p&gt;
&lt;p data-end=&quot;1623&quot; data-start=&quot;1612&quot;&gt;Resultados:&lt;/p&gt;
&lt;ul data-end=&quot;1724&quot; data-start=&quot;1625&quot;&gt;
&lt;li data-end=&quot;1668&quot; data-section-id=&quot;1bwe754&quot; data-start=&quot;1625&quot;&gt;

&lt;/li&gt;
&lt;li data-end=&quot;1724&quot; data-section-id=&quot;1mirgeg&quot; data-start=&quot;1669&quot;&gt;
&lt;strong data-end=&quot;1711&quot; data-start=&quot;1671&quot;&gt;Mediana de velocidad de propagación:&lt;/strong&gt;&amp;nbsp;3.12&lt;strong data-end=&quot;1724&quot; data-start=&quot;1712&quot;&gt;&amp;nbsp;m/s&lt;/strong&gt;
&lt;/li&gt;

&lt;p data-end=&quot;1843&quot; data-start=&quot;1745&quot;&gt;Los valores obtenidos corresponden a una lesión de &lt;strong data-end=&quot;1812&quot; data-start=&quot;1796&quot;&gt;baja rigidez&lt;/strong&gt;, compatible con tejido blando.&lt;/p&gt;
&lt;hr data-end=&quot;1848&quot; data-start=&quot;1845&quot; /&gt;

&lt;p data-end=&quot;2013&quot; data-start=&quot;1875&quot;&gt;Pequeño nódulo sólido hipoecoico de morfología oval, orientación paralela, márgenes circunscritos y sin signos ecográficos de agresividad.&lt;/p&gt;
&lt;p data-end=&quot;2219&quot; data-start=&quot;2015&quot;&gt;Aunque presenta vascularización intralesional al Doppler, este hallazgo por sí solo &lt;strong data-end=&quot;2142&quot; data-start=&quot;2099&quot;&gt;no constituye un criterio de malignidad&lt;/strong&gt;, especialmente cuando la morfología ecográfica permanece claramente benigna.&lt;/p&gt;
&lt;p data-end=&quot;2351&quot; data-start=&quot;2221&quot;&gt;La elastografía Shear Wave demuestra &lt;strong data-end=&quot;2296&quot; data-start=&quot;2258&quot;&gt;baja rigidez (29.20 kPa; 3.12 m/s)&lt;/strong&gt;, hallazgo que favorece aún más una naturaleza benigna.&lt;/p&gt;
&lt;p data-end=&quot;2502&quot; data-start=&quot;2353&quot;&gt;En conjunto, los hallazgos son compatibles con una lesión &lt;strong data-end=&quot;2436&quot; data-start=&quot;2411&quot;&gt;probablemente benigna&lt;/strong&gt;, siendo como primera posibilidad diagnóstica un &lt;strong data-end=&quot;2501&quot; data-start=&quot;2485&quot;&gt;&lt;a data-preview=&quot;&quot; href=&quot;https://www.google.com/search?ved=1t:260882&amp;amp;q=define+fibroadenoma&amp;amp;bbid=6234332233430215054&amp;amp;bpid=4632136742399698101&quot; target=&quot;_blank&quot;&gt;fibroadenoma&lt;/a&gt;&lt;/strong&gt;.&lt;/p&gt;
&lt;p data-end=&quot;2556&quot; data-start=&quot;2504&quot;&gt;&lt;strong data-end=&quot;2556&quot; data-start=&quot;2504&quot;&gt;Clasificación &lt;a data-preview=&quot;&quot; href=&quot;https://www.google.com/search?ved=1t:260882&amp;amp;q=BI-RADS+3+meaning&amp;amp;bbid=6234332233430215054&amp;amp;bpid=4632136742399698101&quot; target=&quot;_blank&quot;&gt;BI-RADS 3&lt;/a&gt; (Probablemente benigno).&lt;/strong&gt;&lt;/p&gt;
&lt;p data-end=&quot;2677&quot; data-start=&quot;2558&quot;&gt;Se recomienda seguimiento ecográfico según las guías BI-RADS (habitualmente a los 6 meses) para documentar estabilidad.&lt;/p&gt;
&lt;hr data-end=&quot;2682&quot; data-start=&quot;2679&quot; /&gt;
&lt;h1 data-end=&quot;2695&quot; data-section-id=&quot;gtwsh5&quot; data-start=&quot;2684&quot;&gt;DISCUSIÓN&lt;/h1&gt;
&lt;p data-end=&quot;2950&quot; data-start=&quot;2697&quot;&gt;El fibroadenoma constituye el tumor sólido benigno más frecuente de la mama en mujeres jóvenes. Ecográficamente suele presentarse como una lesión oval, circunscrita, hipoecoica y orientada paralelamente a la piel, características presentes en este caso.&lt;/p&gt;
&lt;p data-end=&quot;3326&quot; data-start=&quot;2952&quot;&gt;La presencia de flujo intralesional en el Doppler color es un hallazgo relativamente frecuente en fibroadenomas, particularmente en pacientes jóvenes o bajo influencia hormonal. El uso de anticonceptivos hormonales no modifica los criterios de clasificación BI-RADS, aunque puede influir en la actividad vascular y en ligeras variaciones del tamaño de algunos fibroadenomas.&lt;/p&gt;
&lt;p data-end=&quot;3704&quot; data-start=&quot;3328&quot;&gt;La elastografía Shear Wave aporta información complementaria sobre las propiedades mecánicas del tejido. Diversos estudios han demostrado que los fibroadenomas suelen presentar valores de elasticidad inferiores a los observados en carcinomas invasores, los cuales frecuentemente superan los &lt;strong data-end=&quot;3633&quot; data-start=&quot;3619&quot;&gt;80–100 kPa&lt;/strong&gt;, aunque existe cierto solapamiento entre lesiones benignas y malignas.&lt;/p&gt;
&lt;p data-end=&quot;3930&quot; data-start=&quot;3706&quot;&gt;En este caso, la mediana de &lt;strong data-end=&quot;3747&quot; data-start=&quot;3734&quot;&gt;29.20 kPa&lt;/strong&gt; junto con una velocidad de propagación de 3.12&lt;strong data-end=&quot;3802&quot; data-start=&quot;3790&quot;&gt;&amp;nbsp;m/s&lt;/strong&gt; indica una lesión relativamente blanda, en concordancia con los hallazgos morfológicos y reforzando la impresión de benignidad.&lt;/p&gt;
&lt;p data-end=&quot;4176&quot; data-start=&quot;3932&quot;&gt;Es importante destacar que la elastografía &lt;strong data-end=&quot;4017&quot; data-start=&quot;3975&quot;&gt;no sustituye la evaluación morfológica&lt;/strong&gt; ni la clasificación BI-RADS, sino que constituye una herramienta complementaria que incrementa la confianza diagnóstica cuando los hallazgos son concordantes.&lt;/p&gt;

&lt;p data-end=&quot;1578&quot; data-start=&quot;1453&quot;&gt;Quantitative Shear Wave Elastography (SWE) was performed with &lt;strong data-end=&quot;1552&quot; data-start=&quot;1515&quot;&gt;ten (10) independent measurements&lt;/strong&gt; obtained from the lesion.&lt;/p&gt;
&lt;p data-end=&quot;1588&quot; data-start=&quot;1580&quot;&gt;Results:&lt;/p&gt;

&lt;p data-end=&quot;1795&quot; data-start=&quot;1700&quot;&gt;These measurements indicate a &lt;strong data-end=&quot;1754&quot; data-start=&quot;1730&quot;&gt;low-stiffness lesion&lt;/strong&gt;, consistent with relatively soft tissue.&lt;/p&gt;
&lt;hr data-end=&quot;1800&quot; data-start=&quot;1797&quot; /&gt;
&lt;h1 data-end=&quot;1818&quot; data-section-id=&quot;mepcrx&quot; data-start=&quot;1802&quot;&gt;&lt;span role=&quot;text&quot;&gt;&lt;strong data-end=&quot;1818&quot; data-start=&quot;1804&quot;&gt;IMPRESSION&lt;/strong&gt;&lt;/span&gt;&lt;/h1&gt;
&lt;p data-end=&quot;1977&quot; data-start=&quot;1820&quot;&gt;Small solid hypoechoic breast nodule with oval morphology, parallel orientation, circumscribed margins, and no sonographic features suggestive of malignancy.&lt;/p&gt;
&lt;p data-end=&quot;2215&quot; data-start=&quot;1979&quot;&gt;Although the lesion demonstrates internal vascularity on Color Doppler imaging, this finding alone &lt;strong data-end=&quot;2126&quot; data-start=&quot;2078&quot;&gt;is not considered a criterion for malignancy&lt;/strong&gt;, particularly when the morphologic ultrasound features remain characteristically benign.&lt;/p&gt;
&lt;p data-end=&quot;2337&quot; data-start=&quot;2217&quot;&gt;Shear Wave Elastography demonstrates &lt;strong data-end=&quot;2300&quot; data-start=&quot;2254&quot;&gt;low tissue stiffness (29.20 kPa; 3.12 m/s)&lt;/strong&gt;, further supporting a benign nature.&lt;/p&gt;
&lt;p data-end=&quot;2485&quot; data-start=&quot;2339&quot;&gt;Overall, the imaging findings are most consistent with a &lt;strong data-end=&quot;2422&quot; data-start=&quot;2396&quot;&gt;probably benign lesion&lt;/strong&gt;, with &lt;strong data-end=&quot;2445&quot; data-start=&quot;2429&quot;&gt;fibroadenoma&lt;/strong&gt; representing the most likely diagnosis.&lt;/p&gt;
&lt;p data-end=&quot;2528&quot; data-start=&quot;2487&quot;&gt;&lt;strong data-end=&quot;2528&quot; data-start=&quot;2487&quot;&gt;BI-RADS Category 3 – Probably Benign.&lt;/strong&gt;&lt;/p&gt;
&lt;p data-end=&quot;2630&quot; data-start=&quot;2530&quot;&gt;Short-term ultrasound follow-up (typically at 6 months) is recommended to document lesion stability.&lt;/p&gt;
&lt;hr data-end=&quot;2635&quot; data-start=&quot;2632&quot; /&gt;
&lt;h1 data-end=&quot;2653&quot; data-section-id=&quot;1xzp9gm&quot; data-start=&quot;2637&quot;&gt;&lt;span role=&quot;text&quot;&gt;&lt;strong data-end=&quot;2653&quot; data-start=&quot;2639&quot;&gt;DISCUSSION&lt;/strong&gt;&lt;/span&gt;&lt;/h1&gt;
&lt;p data-end=&quot;2901&quot; data-start=&quot;2655&quot;&gt;Fibroadenoma is the most common benign solid breast tumor in young women. On ultrasound, it typically appears as an oval, circumscribed, hypoechoic lesion with a parallel orientation to the skin, all of which are demonstrated in the present case.&lt;/p&gt;
&lt;p data-end=&quot;3209&quot; data-start=&quot;2903&quot;&gt;Internal vascularity on Color Doppler imaging is a relatively common finding in fibroadenomas, particularly in younger women or in those under hormonal influence. Although hormonal contraceptives may influence vascularity and occasionally lesion size, they &lt;strong data-end=&quot;3208&quot; data-start=&quot;3160&quot;&gt;do not alter the BI-RADS assessment criteria&lt;/strong&gt;.&lt;/p&gt;
&lt;p data-end=&quot;3614&quot; data-start=&quot;3211&quot;&gt;Shear Wave Elastography provides complementary quantitative information regarding the mechanical properties of breast tissue. Numerous studies have shown that fibroadenomas generally exhibit significantly lower elasticity values than invasive breast carcinomas, which frequently demonstrate stiffness values exceeding &lt;strong data-end=&quot;3543&quot; data-start=&quot;3529&quot;&gt;80–100 kPa&lt;/strong&gt;, although some overlap between benign and malignant lesions may occur.&lt;/p&gt;
&lt;p data-end=&quot;3859&quot; data-start=&quot;3616&quot;&gt;In this case, the &lt;strong data-end=&quot;3668&quot; data-start=&quot;3634&quot;&gt;median elasticity of 29.20 kPa&lt;/strong&gt; together with a &lt;strong data-end=&quot;3727&quot; data-start=&quot;3685&quot;&gt;median shear wave velocity of 3.12 m/s&lt;/strong&gt; indicates a relatively soft lesion, consistent with the benign morphologic appearance and further increasing diagnostic confidence.&lt;/p&gt;
&lt;p data-end=&quot;4172&quot; data-start=&quot;3861&quot;&gt;It is important to emphasize that &lt;strong data-end=&quot;3996&quot; data-start=&quot;3895&quot;&gt;Shear Wave Elastography does not replace conventional B-mode ultrasound or BI-RADS classification&lt;/strong&gt;, but rather serves as a valuable complementary technique that enhances diagnostic confidence when quantitative stiffness measurements are concordant with morphologic findings.&lt;/p&gt;

Debido a la escasez de valores de referencia elastográficos para este tipo de lesión en la literatura médica actual, la acumulación y publicación de casos similares podría contribuir al establecimiento de parámetros de referencia futuros y ampliar el conocimiento sobre las características biomecánicas de los endometriomas ováricos.&lt;/p&gt;&lt;h2&gt;DISCUSIÓN&lt;/h2&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Los endometriomas constituyen una de las manifestaciones más frecuentes de la &lt;a data-preview=&quot;&quot; href=&quot;https://www.google.com/search?ved=1t:260882&amp;amp;q=endometriosis&amp;amp;bbid=6234332233430215054&amp;amp;bpid=3416160129309205271&quot; target=&quot;_blank&quot;&gt;endometriosis&lt;/a&gt; ovárica y suelen presentarse en mujeres con dolor pélvico crónico, &lt;a data-preview=&quot;&quot; href=&quot;https://www.google.com/search?ved=1t:260882&amp;amp;q=define+dismenorrea&amp;amp;bbid=6234332233430215054&amp;amp;bpid=3416160129309205271&quot; target=&quot;_blank&quot;&gt;dismenorrea&lt;/a&gt; e infertilidad. La ecografía convencional continúa siendo el principal método de imagen para su diagnóstico; sin embargo, la Elastografía Shear Wave ofrece la posibilidad de cuantificar objetivamente la rigidez de los tejidos y aportar información adicional sobre la composición y el comportamiento biológico de la lesión.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Los valores de rigidez observados en este caso sugieren una pared relativamente firme, probablemente relacionada con los procesos crónicos de inflamación, fibrosis y hemorragias repetidas que caracterizan a los quistes endometriósicos. Aunque actualmente la SWE no forma parte de los algoritmos diagnósticos estándar para la endometriosis, la evidencia emergente indica que la evaluación elastográfica podría convertirse en una herramienta complementaria de gran utilidad para la caracterización de masas anexiales y para la diferenciación entre lesiones benignas y potencialmente malignas.&lt;/p&gt;&lt;p&gt;Serán necesarios estudios con un mayor número de pacientes para determinar la reproducibilidad, el valor diagnóstico y los rangos de referencia de las mediciones obtenidas mediante Elastografía Shear Wave en los endometriomas ováricos.&lt;/p&gt;&lt;h2 style=&quot;text-align: justify;&quot;&gt;Left Ovarian Endometrioma Evaluated with Shear Wave Elastography (SWE): Sonographic, Doppler and Elastographic Correlation&lt;/h2&gt;&lt;p&gt;&lt;br /&gt;&lt;/p&gt;&lt;h2&gt;PATIENT HISTORY&lt;/h2&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;A 24-year-old female presented to the emergency department with severe pain localized to the left iliac fossa. She reported a history of highly painful menstrual periods accompanied by nausea, vomiting, and diarrhea, raising a strong clinical suspicion of endometriosis syndrome. The patient also had a history of primary infertility of several years&#39; duration.&lt;/p&gt;&lt;h2&gt;TRANSVAGINAL ULTRASOUND FINDINGS&lt;/h2&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Transvaginal sonography demonstrated a uterus measuring approximately 9.12 × 5.61 × 4.69 cm. The endometrium appeared thickened, measuring approximately 18.1 mm (Figure 1).&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;A complex cystic lesion was identified in the left ovarian region, with an estimated volume of approximately 51.4 cc (Figure 2).&lt;/p&gt;&lt;h2&gt;COLOR DOPPLER FINDINGS&lt;/h2&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Color Doppler examination demonstrated peripheral vascular flow within the deeper portion of the lesion (Figure 3).&lt;/p&gt;&lt;h2&gt;SHEAR WAVE ELASTOGRAPHY (SWE) FINDINGS&lt;/h2&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Ten valid measurements were obtained from the anterior wall of the lesion.

Additional similar cases should be accumulated and analyzed to establish future reference values for SWE parameters in this type of lesion.&lt;/p&gt;&lt;h2&gt;DISCUSSION&lt;/h2&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Endometriomas are among the most common manifestations of ovarian endometriosis and frequently occur in women presenting with chronic pelvic pain, dysmenorrhea, and infertility. Conventional ultrasound remains the primary imaging modality for diagnosis; however, Shear Wave Elastography offers the opportunity to objectively quantify tissue stiffness and may provide additional information regarding lesion composition and biological behavior.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;The stiffness values observed in this case suggest a relatively firm lesion wall, likely reflecting the chronic inflammatory process, fibrosis, and recurrent hemorrhagic episodes characteristic of endometriotic cysts. Although SWE is not currently included in standard diagnostic algorithms for endometriosis, elastographic assessment may become a valuable complementary tool for the characterization of adnexal masses and for differentiating benign from potentially malignant lesions.&lt;/p&gt;&lt;p&gt;Further studies involving larger patient populations are required to determine the reproducibility, diagnostic value, and reference ranges of SWE measurements in ovarian endometriomas.&lt;/p&gt;&lt;table align=&quot;center&quot;

Aunque estos resultados no deben considerarse todavía criterios diagnósticos definitivos debido a la ausencia de valores de referencia ampliamente aceptados, representan una observación de gran interés clínico y académico.&lt;/p&gt;&lt;p&gt;La incorporación de técnicas avanzadas como la elastografía Shear Wave permite obtener información adicional sobre las &lt;a data-preview=&quot;&quot; href=&quot;https://www.google.com/search?ved=1t:260882&amp;amp;q=biomechanical+properties+of+tissues&amp;amp;bbid=6234332233430215054&amp;amp;bpid=7527620009872161462&quot; target=&quot;_blank&quot;&gt;propiedades biomecánicas de los tejidos&lt;/a&gt;, complementando la evaluación morfológica convencional.

As part of the trauma evaluation, a computed tomography (CT) scan was performed to rule out internal injuries.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Incidentally, a mixed right adnexal mass was identified and reported as a probable ovarian teratoma (Figures 7 and 8), prompting further sonographic assessment.&lt;/p&gt;&lt;h2&gt;SONOGRAPHIC FINDINGS&lt;/h2&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;A transabdominal pelvic ultrasound examination was performed with a fully distended urinary bladder, as the patient had never been sexually active.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;The study demonstrated a complex cystic mass arising from the right ovary (Figure 1), measuring approximately 6.09 × 11.3 × 6.75 cm.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;The lesion was predominantly cystic and contained a rounded solid mural nodule attached to its anterior wall (Figure 4). Along the inferior margin of this nodule, a linear hyperechoic structure associated with marked posterior acoustic shadowing was identified (Figure 1), consistent with calcified dermoid components.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;These sonographic findings are characteristic of a Rokitansky nodule (dermoid plug), one of the most distinctive imaging features of a mature cystic teratoma.&lt;/p&gt;&lt;h2&gt;COLOR DOPPLER FINDINGS&lt;/h2&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Color Doppler evaluation demonstrated minimal vascularity, showing only a small amount of peripheral blood flow within the deepest portion of the lesion (Figure 2), without evidence of significant neovascularization.&lt;/p&gt;&lt;h2&gt;SHEAR WAVE ELASTOGRAPHY (SWE)&lt;/h2&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;a data-preview=&quot;&quot; href=&quot;https://www.google.com/search?ved=1t:260882&amp;amp;q=define+Shear+Wave+Elastography&amp;amp;bbid=6234332233430215054&amp;amp;bpid=7527620009872161462&quot; target=&quot;_blank&quot;&gt;Shear Wave Elastography&lt;/a&gt; was performed over the solid component corresponding to the Rokitansky nodule (Figures 5 and 6).&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;The obtained measurements were:&lt;/p&gt;&lt;ul data-spread=&quot;false&quot;&gt;&lt;li&gt;Median stiffness: 9.74 kPa&lt;/li&gt;&lt;li&gt;Shear wave velocity: 1.83 m/s&lt;/li&gt;&lt;/ul&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;These values indicate low tissue stiffness within the solid component of the lesion.&lt;/p&gt;&lt;h2&gt;CT CORRELATION&lt;/h2&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Computed tomography (Figures 7 and 8) confirmed the presence of a right adnexal cystic lesion containing components of different densities, consistent with a mature cystic teratoma, showing excellent correlation with the ultrasound findings.&lt;/p&gt;&lt;h2&gt;DIAGNOSIS&lt;/h2&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Mature cystic teratoma of the right ovary (dermoid cyst) with a Rokitansky nodule.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;The sonographic, Doppler, and CT findings are highly characteristic of this entity and allow a confident diagnosis. The echogenic mural nodule associated with posterior acoustic shadowing corresponds to the classic Rokitansky nodule typically observed in mature cystic teratomas.&lt;/p&gt;&lt;h2&gt;COMMENT ON THE CONTRIBUTION OF SHEAR WAVE ELASTOGRAPHY&lt;/h2&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;To the best of our knowledge, and based on the currently available literature, although elastography has been applied to the evaluation of ovarian masses, reports specifically describing quantitative Shear Wave Elastography assessment of a Rokitansky nodule within a mature cystic teratoma are exceedingly rare.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;In this case, the measured stiffness of 9.74 kPa and shear wave velocity of 1.83 m/s suggest a low-stiffness tissue component, consistent with the benign nature of the lesion. Although these findings should not yet be regarded as definitive diagnostic criteria due to the lack of widely accepted reference values, they represent an observation of significant clinical and academic interest.&lt;/p&gt;&lt;p&gt;The incorporation of advanced ultrasound techniques such as Shear Wave Elastography provides additional information regarding the biomechanical properties of tissues and complements conventional morphological assessment. The systematic collection of similar data may contribute in the future to the establishment of national and international reference parameters for the characterization of benign and malignant ovarian lesions, thereby expanding the diagnostic value of modern ultrasound imaging.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;b&gt;NOTE: At the time of the examination, we assumed this might represent a pioneering study in the Dominican Republic. However, after consulting available information through AI-assisted literature review, the following was reported (quote):&lt;/b&gt;&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;b&gt;“To the extent of the available literature, there are no widely accepted reference values for shear wave elastography specifically for Rokitansky nodules (dermoid plugs) in mature cystic ovarian teratomas. Most studies on ovarian teratomas have focused on morphological ultrasound findings, Doppler evaluation, and MRI characteristics rather than quantitative SWE measurements of the mural nodule.”&lt;/b&gt;&lt;/p&gt;&lt;p&gt;&lt;b&gt;“Your observation is particularly interesting because it could represent a useful case for an ovarian elastography database. There is currently a significant lack of publications reporting SWE values of dermoid plugs. Therefore, cases with histopathological correlation could provide valuable information to the medical literature.”&lt;/b&gt;&lt;/p&gt;&lt;br /&gt;&lt;br /&gt;&lt;table align=&quot;center&quot; cellpadding=&quot;0&quot;

The patient reports having spontaneously passed approximately 87 kidney stones throughout his lifetime, which he has kept as evidence of his condition. He also states that he regularly takes natural remedies purchased abroad and believes these treatments prevent the severe pain typically associated with stone passage. At the time of examination, he showed no clinical signs or symptoms suggestive of acute renal colic.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;strong&gt;SONOGRAPHIC FINDINGS&lt;/strong&gt;&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;a data-preview=&quot;&quot; href=&quot;https://www.google.com/search?ved=1t:260882&amp;amp;q=define+Ultrasound&amp;amp;bbid=6234332233430215054&amp;amp;bpid=8045614482878116664&quot; target=&quot;_blank&quot;&gt;Ultrasound&lt;/a&gt; examination demonstrates both kidneys in their normal anatomical location. Multiple hyperechoic foci with posterior acoustic shadowing are identified within both kidneys, consistent with bilateral nephrolithiasis.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;At least two calculi are visualized within the right kidney. The renal contour appears irregular and deformed, suggesting chronic cortical scarring and longstanding renal damage.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;Three calculi are identified within the left kidney. Mild dilatation of the pelvicalyceal collecting system is also present, consistent with Grade I hydronephrosis. Similar contour irregularity and deformation of the left kidney are noted, compatible with chronic renal scarring related to recurrent obstructive and infectious processes.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;No perirenal fluid collections or sonographic signs of high-grade acute urinary obstruction are observed.&lt;/p&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;strong&gt;CONCLUSION&lt;/strong&gt;&lt;/p&gt;&lt;ul data-spread=&quot;false&quot;&gt;&lt;li&gt;Bilateral multiple nephrolithiasis.&lt;/li&gt;&lt;li&gt;Grade I hydronephrosis of the left kidney.&lt;/li&gt;&lt;li&gt;Bilateral renal contour deformity and cortical irregularity suggestive of chronic scarring secondary to longstanding recurrent stone disease.&lt;/li&gt;&lt;li&gt;Sonographic findings are compatible with probable bilateral chronic pyelonephritis. Clinical correlation, renal function assessment, and specialized urological evaluation are recommended.&lt;/li&gt;&lt;/ul&gt;&lt;p class=&quot;isSelectedEnd&quot;&gt;&lt;strong&gt;CASE DISCUSSION&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;The occurrence of numerous episodes of spontaneous stone passage over several decades, together with the structural abnormalities observed in both kidneys, illustrates the progressive renal damage that may result from recurrent nephrolithiasis. Ultrasound plays a crucial role in the evaluation of these patients by identifying renal calculi, assessing the degree of urinary obstruction, and detecting indirect signs of chronic renal injury. Correlation of sonographic findings with clinical history and laboratory data is essential for establishing appropriate follow-up strategies and preventing further deterioration of renal function.&lt;/p&gt;&lt;table align=&quot;center&quot;

&lt;p data-end=&quot;1383&quot; data-start=&quot;1375&quot;&gt;(Foto 5)&lt;/p&gt;
&lt;p data-end=&quot;1574&quot; data-start=&quot;1385&quot;&gt;Los valores obtenidos indican una lesión de baja rigidez relativa, hallazgo que sugiere una composición tisular poco fibrosa y sin evidencia de marcada desmoplasia o endurecimiento tumoral.&lt;/p&gt;
&lt;h2 data-end=&quot;1588&quot; data-section-id=&quot;1ax20ga&quot; data-start=&quot;1576&quot;&gt;DISCUSIÓN&lt;/h2&gt;
&lt;p data-end=&quot;1922&quot; data-start=&quot;1590&quot;&gt;Las masas renales sólidas constituyen un hallazgo frecuente en la práctica de la imagenología moderna. Aunque la &lt;a data-preview=&quot;&quot; href=&quot;https://www.google.com/search?ved=1t:260882&amp;amp;q=define+tomograf%C3%ADa+computarizada+comparison+with+ultrasound&amp;amp;bbid=6234332233430215054&amp;amp;bpid=1812524705631064606&quot; target=&quot;_blank&quot;&gt;tomografía computarizada&lt;/a&gt; y la resonancia magnética continúan siendo los métodos de referencia para su caracterización, la sonografía aporta información valiosa en la detección inicial y el seguimiento de estas lesiones.&lt;/p&gt;
&lt;p data-end=&quot;2151&quot; data-start=&quot;1924&quot;&gt;En este caso, la lesión presenta características ecográficas compatibles con una neoplasia renal sólida de bajo grado de vascularización. El patrón observado permite considerar dentro del diagnóstico diferencial entidades como:&lt;/p&gt;

&lt;/li&gt;
&lt;/ul&gt;
&lt;p data-end=&quot;2703&quot; data-start=&quot;2289&quot;&gt;Los hallazgos elastográficos son particularmente interesantes debido a que la lesión muestra una rigidez relativamente baja (3.71 kPa), valor inferior al reportado habitualmente en muchos tumores renales malignos. Sin embargo, existe un importante solapamiento entre los valores elastográficos de lesiones benignas y malignas, por lo que la elastografía no permite establecer un diagnóstico histológico definitivo.&lt;/p&gt;
&lt;h2 data-end=&quot;2749&quot; data-section-id=&quot;e9cl46&quot; data-start=&quot;2705&quot;&gt;IMPORTANCIA DE LA ELASTOGRAFÍA SHEAR WAVE&lt;/h2&gt;
&lt;p data-end=&quot;3070&quot; data-start=&quot;2751&quot;&gt;La elastografía Shear Wave representa una herramienta complementaria prometedora en la evaluación de masas renales. Además de aportar información cuantitativa sobre las propiedades mecánicas del tejido, permite caracterizar de forma no invasiva la rigidez tumoral y documentar cambios evolutivos durante el seguimiento.&lt;/p&gt;
&lt;p data-end=&quot;3365&quot; data-start=&quot;3072&quot;&gt;Aunque actualmente no sustituye los métodos diagnósticos convencionales ni el estudio histopatológico, su incorporación sistemática puede contribuir a mejorar la caracterización multiparamétrica de las lesiones renales, especialmente cuando se integra con los hallazgos sonográficos y Doppler.&lt;/p&gt;

&lt;p data-end=&quot;364&quot; data-start=&quot;130&quot;&gt;A 71-year-old male with a history of Type 2 Diabetes Mellitus controlled with oral antidiabetic medication was referred for a routine abdominal ultrasound examination. The patient reported no urinary symptoms at the time of the study.&lt;/p&gt;
&lt;h2 data-end=&quot;393&quot; data-section-id=&quot;1fb1nig&quot; data-start=&quot;366&quot;&gt;&lt;span role=&quot;text&quot;&gt;&lt;strong data-end=&quot;393&quot; data-start=&quot;369&quot;&gt;SONOGRAPHIC FINDINGS&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;p data-end=&quot;561&quot; data-start=&quot;395&quot;&gt;Abdominal ultrasound demonstrated a liver of normal size (13.7 cm) with mild diffuse increased echogenicity, consistent with &lt;strong data-end=&quot;549&quot; data-start=&quot;520&quot;&gt;Grade I hepatic steatosis&lt;/strong&gt; (Figure 1).&lt;/p&gt;
&lt;p data-end=&quot;806&quot; data-start=&quot;563&quot;&gt;The right kidney showed a solid lesion located at the lower pole. The mass was round, well-circumscribed, mildly heterogeneous, and predominantly solid in appearance. Its approximate dimensions were &lt;strong data-end=&quot;787&quot; data-start=&quot;762&quot;&gt;3.62 × 3.93 × 3.93 cm&lt;/strong&gt; (Figures 2 and 3).&lt;/p&gt;
&lt;p data-end=&quot;919&quot; data-start=&quot;808&quot;&gt;The left kidney demonstrated normal morphology, size, and echogenicity, without focal abnormalities (Figure 6).&lt;/p&gt;

&lt;p data-end=&quot;1105&quot; data-start=&quot;952&quot;&gt;Color Doppler evaluation revealed mild peripheral vascularity surrounding the lesion, with no significant intralesional blood flow identified (Figure 4).&lt;/p&gt;
&lt;h2 data-end=&quot;1143&quot; data-section-id=&quot;1a3vmzc&quot; data-start=&quot;1107&quot;&gt;&lt;span role=&quot;text&quot;&gt;&lt;strong data-end=&quot;1143&quot; data-start=&quot;1110&quot;&gt;SHEAR WAVE ELASTOGRAPHY (SWE)&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;p data-end=&quot;1201&quot; data-start=&quot;1145&quot;&gt;Ten valid SWE measurements were obtained, demonstrating:&lt;/p&gt;
&lt;ul data-end=&quot;1271&quot; data-start=&quot;1203&quot;&gt;
&lt;li data-end=&quot;1235&quot; data-section-id=&quot;1azqokc&quot; data-start=&quot;1203&quot;&gt;

&lt;/li&gt;

&lt;/li&gt;
&lt;/ul&gt;
&lt;p data-end=&quot;1283&quot; data-start=&quot;1273&quot;&gt;(Figure 5)&lt;/p&gt;
&lt;p data-end=&quot;1480&quot; data-start=&quot;1285&quot;&gt;These findings indicate a lesion with relatively low stiffness, suggesting tissue composition with limited fibrosis and no evidence of marked desmoplastic reaction or significant tumor hardening.&lt;/p&gt;
&lt;h2 data-end=&quot;1499&quot; data-section-id=&quot;1geyd9h&quot; data-start=&quot;1482&quot;&gt;&lt;span role=&quot;text&quot;&gt;&lt;strong data-end=&quot;1499&quot; data-start=&quot;1485&quot;&gt;DISCUSSION&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;p data-end=&quot;1806&quot; data-start=&quot;1501&quot;&gt;Solid renal masses are a common finding in modern diagnostic imaging. Although computed tomography (CT) and magnetic resonance imaging (MRI) remain the reference standards for lesion characterization, ultrasound provides valuable information for the initial detection and follow-up of these abnormalities.&lt;/p&gt;
&lt;p data-end=&quot;1970&quot; data-start=&quot;1808&quot;&gt;In this case, the lesion demonstrates sonographic features compatible with a solid renal neoplasm exhibiting low vascularity. The differential diagnosis includes:&lt;/p&gt;
&lt;ul data-end=&quot;2089&quot; data-start=&quot;1972&quot;&gt;
&lt;li data-end=&quot;2011&quot; data-section-id=&quot;1jtjmfh&quot; data-start=&quot;1972&quot;&gt;

Fat-poor angiomyolipoma
&lt;/li&gt;
&lt;/ul&gt;
&lt;p data-end=&quot;2468&quot; data-start=&quot;2091&quot;&gt;The elastographic findings are particularly noteworthy because the lesion exhibited relatively low stiffness (3.71 kPa), a value lower than that reported for many malignant renal tumors. However, considerable overlap exists between the elastographic values of benign and malignant renal lesions; therefore, elastography alone cannot establish a definitive histologic diagnosis.&lt;/p&gt;
&lt;h2 data-end=&quot;2512&quot; data-section-id=&quot;sjd0e4&quot; data-start=&quot;2470&quot;&gt;&lt;span role=&quot;text&quot;&gt;&lt;strong data-end=&quot;2512&quot; data-start=&quot;2473&quot;&gt;THE ROLE OF SHEAR WAVE ELASTOGRAPHY&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;p data-end=&quot;2806&quot; data-start=&quot;2514&quot;&gt;Shear Wave Elastography is an emerging complementary tool in the evaluation of renal masses. In addition to providing quantitative information regarding tissue mechanical properties, it allows noninvasive assessment of tumor stiffness and facilitates longitudinal monitoring during follow-up.&lt;/p&gt;
&lt;p data-end=&quot;3082&quot; data-start=&quot;2808&quot;&gt;Although SWE does not currently replace conventional imaging methods or histopathological evaluation, its systematic incorporation may enhance the multiparametric characterization of renal lesions, particularly when integrated with grayscale ultrasound and Doppler findings.&lt;/p&gt;

&lt;p data-end=&quot;259&quot; data-start=&quot;46&quot;&gt;La combinación de hallazgos morfológicos, Doppler y elastográficos en esta paciente joven configura un patrón de alta sospecha para malignidad mamaria, a pesar de la edad y del antecedente previo de fibroadenomas.&lt;/p&gt;
&lt;p data-end=&quot;321&quot; data-start=&quot;261&quot;&gt;El nódulo presenta varios &lt;a data-preview=&quot;&quot; href=&quot;https://www.google.com/search?ved=1t:260882&amp;amp;q=suspicious+ultrasound+criteria+breast&amp;amp;bbid=6234332233430215054&amp;amp;bpid=4877207194938156691&quot; target=&quot;_blank&quot;&gt;criterios ecográficos sospechosos&lt;/a&gt;:&lt;/p&gt;

&lt;/li&gt;
&lt;/ul&gt;
&lt;p data-end=&quot;610&quot; data-start=&quot;496&quot;&gt;A esto se suma un hallazgo particularmente relevante: la elevada rigidez tisular en elastografía shear wave (SWE).&lt;/p&gt;
&lt;p data-end=&quot;634&quot; data-start=&quot;612&quot;&gt;Los valores obtenidos:&lt;/p&gt;
&lt;ul data-end=&quot;689&quot; data-start=&quot;635&quot;&gt;

&lt;strong data-end=&quot;689&quot; data-start=&quot;666&quot;&gt;Velocidad: 4.43 m/s&lt;/strong&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;p data-end=&quot;1033&quot; data-start=&quot;691&quot;&gt;se encuentran claramente por encima de los rangos habitualmente descritos para fibroadenomas benignos clásicos, que generalmente muestran valores considerablemente menores. En múltiples series clínicas, lesiones malignas suelen superar los 50-60 kPa, aunque existe inevitable superposición entre lesiones benignas proliferativas y carcinomas.&lt;/p&gt;
&lt;p data-end=&quot;1281&quot; data-start=&quot;1035&quot;&gt;Debe señalarse que algunos fibroadenomas juveniles, fibroadenomas complejos, lesiones esclerosantes o &lt;a data-preview=&quot;&quot; href=&quot;https://www.google.com/search?ved=1t:260882&amp;amp;q=define+phyllodes+tumors&amp;amp;bbid=6234332233430215054&amp;amp;bpid=4877207194938156691&quot; target=&quot;_blank&quot;&gt;tumores filoides&lt;/a&gt; pueden mostrar rigidez aumentada y simular malignidad tanto en ecografía como en SWE. Sin embargo, la asociación simultánea de:&lt;/p&gt;

&lt;/ul&gt;
&lt;p data-end=&quot;1462&quot; data-start=&quot;1371&quot;&gt;justifica plenamente la categorización &lt;strong data-end=&quot;1425&quot; data-start=&quot;1410&quot;&gt;BI-RADS 4-5&lt;/strong&gt; y obliga a confirmación histológica.&lt;/p&gt;
&lt;p data-end=&quot;1573&quot; data-start=&quot;1464&quot;&gt;La ausencia de adenopatías axilares visibles es un hallazgo favorable, aunque no excluye malignidad temprana.&lt;/p&gt;

Más allá de la valoración morfológica proporcionada por la sonografía, la SWE ofrece información cuantitativa sobre la rigidez tisular, mejorando la caracterización de las lesiones e incrementando la confianza diagnóstica. En casos con hallazgos sonográficos dudosos o sospechosos, valores marcadamente elevados de rigidez pueden reforzar la sospecha de malignidad y ayudar a priorizar la biopsia y la conducta clínica. Aunque la SWE nunca debe sustituir la confirmación histopatológica, su integración dentro de protocolos multiparamétricos de ultrasonido mamario representa una herramienta complementaria de gran valor, capaz de mejorar la estratificación del riesgo, reducir la falsa sensación de benignidad en lesiones aparentemente inocentes y contribuir a la detección más temprana de cáncer mamario clínicamente significativo. *&lt;/b&gt;&lt;/div&gt;&lt;section class=&quot;text-token-text-primary w-full focus:outline-none [--shadow-height:45px] has-data-writing-block:pointer-events-none has-data-writing-block:-mt-(--shadow-height) has-data-writing-block:pt-(--shadow-height) [&amp;amp;:has([data-writing-block])&amp;gt;*]:pointer-events-auto R6Vx5W_threadScrollVars scroll-mb-[calc(var(--scroll-root-safe-area-inset-bottom,0px)+var(--thread-response-height))] scroll-mt-(--header-height)&quot;

&lt;/li&gt;
&lt;/ul&gt;&lt;p data-end=&quot;1942&quot; data-start=&quot;1815&quot;&gt;An additional highly relevant finding is the markedly increased tissue stiffness demonstrated on shear wave elastography (SWE).&lt;/p&gt;&lt;p data-end=&quot;1960&quot; data-start=&quot;1944&quot;&gt;Obtained values:&lt;/p&gt;&lt;ul data-end=&quot;2017&quot; data-start=&quot;1961&quot;&gt;

Beyond the morphologic assessment provided by ultrasound, SWE offers quantitative information regarding tissue stiffness, improving lesion characterization and increasing diagnostic confidence. In cases with equivocal or suspicious sonographic findings, markedly elevated stiffness values may reinforce suspicion for malignancy and help prioritize biopsy and clinical management. Although SWE should never replace histopathological confirmation, its integration into multiparametric breast ultrasound protocols represents a valuable complementary tool that may improve risk stratification, reduce false reassurance in apparently benign lesions, and contribute to earlier detection of clinically significant breast cancer.&lt;/b&gt;&lt;/p&gt;&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;br /&gt;&lt;/p&gt;&lt;div class=&quot;separator&quot;
