Ultrasound Features of Uterine Sarcomas.

Uterine sarcomas include leiomyosarcoma, smooth muscle tumor of uncertain malignant potential, endometrial stromal sarcoma, undifferentiated sarcoma, carcinosarcoma, adenosarcoma, and rhabdomyosarcoma. Leiomyosarcomas are the most common uterine sarcomas and list some potential others. Uterine sarcomas have a wide histopathological spectrum that may display various imaging features, making the preoperative diagnosis challenging. The purpose of this review was to discuss the clinical features of uterine sarcomas, as well as their imaging appearances and characteristics. From this, practitioners can ensure that suspicious sonographic findings of uterine sarcomas, including a large-size, heterogeneous echotexture, central cystic change or necrosis, and hypervascularity, are recognized to facilitate further evaluation. Familiarity with the clinical presentations and imaging features of uterine sarcomas can lead to a more accurate diagnosis and appropriate management.
