Estudio Nódulo Mamario con Elastografia Shear Wave
Caso Clínico: Nódulos Mamarios y Evaluación con Elastografía Shear Wave (SWE)
Hallazgos sonográficos:
-
Mama derecha:
-
Nódulo sólido hipoecogénico, ovalado, de contornos regulares, con eje mayor paralelo a la piel.
-
Tamaño: 2.92 × 1.73 cm.
-
Localización: radial 07 (foto 1).
-
Doppler color: discreto flujo vascular interno (foto 4).
-
-
Mama izquierda:
-
Se identifican dos nódulos sólidos hipoecogénicos con morfología y ecogenicidad similares a los descritos en la mama derecha.
-
Tamaños:
-
2.15 × 1.02 cm (foto 2).
-
1.38 × 0.99 cm (foto 3).
-
-
-
Axila derecha: sin adenopatías patológicas detectables (foto 10).
Elastografía Shear Wave (SWE):
-
Se estudió el nódulo de mayor tamaño (derecho), que corresponde al más doloroso y clínicamente relevante.
-
Número de mediciones: 10.
-
Mediana: 54.20 KPa.
-
Velocidad de transmisión: 4.25 m/s.
Case Report: Breast Nodules Evaluated with Shear Wave Elastography (SWE)
Background:
A 49-year-old female patient under follow-up for painful solid nodules in both breasts. Past medical history includes total hysterectomy due to uterine fibroids associated with severe menorrhagia, which led to chronic iron-deficiency anemia. She also has hypothyroidism secondary to Hashimoto’s thyroiditis.
Sonographic Findings:
-
Right breast:
-
Solid hypoechoic nodule, oval in shape, with regular margins and wider-than-tall orientation.
-
Size: 2.92 × 1.73 cm.
-
Location: radial 07 (image 1).
-
Color Doppler: mild internal vascular flow (image 4).
-
-
Left breast:
-
Two solid hypoechoic nodules, showing the same sonographic features as the right-sided lesion.
-
Sizes:
-
2.15 × 1.02 cm (image 2).
-
1.38 × 0.99 cm (image 3).
-
-
-
Right axilla: no sonographically detectable pathological lymph nodes (image 10).
Shear Wave Elastography (SWE):
-
The largest and most painful nodule (right breast) was selected for elastography assessment.
-
Number of measurements: 10.
-
Median stiffness: 54.20 KPa.
-
Shear wave speed: 4.25 m/s.
Interpretation:
The combined findings of breast ultrasound, Color Doppler, and SWE are highly suggestive of fibroadenoma.
📌 Histopathological correlation remains the gold standard for definitive diagnosis.
