Sonographic characterization and surveillance of paravaginal smooth muscle tumor of uncertain malignant potential
JOURNAL OF CLINICAL ULTRASOUND(2022)
摘要
Sonographic characterization and surveillance of paravaginal smooth muscle tumor of uncertain malignant potential. (A1) Transvaginal ultrasound with probe placed over the right vaginal wall, showing a well-defined round mass with regular contours, a mostly hypoechoic and heterogeneous echotexture, and edge shadowing, deep to the right distal third of the right vagina. (A2) Multifrequency linear probe (9-14 MHz) placed over the right labium majus revealing hyperechoic striations (arrows on A1-A2) and central flow (arrowheads on A2). (B1) Resected solid white-tan mass of bland consistency. (B2) Hematoxylin-eosin microscopy (40X) showing fusiform cells, with mild to moderate atypia. (C1) Repeat transvaginal ultrasound six-years later showing a recurrent solid oval-shaped mass with regular contour, a mostly hypoechoic heterogeneous echotexture, and an anechoic area inside the solid mass (asterisk on C2) that could represent a focus of necrosis.
