摘要: Uterine leiomyosarcoma, initially diagnosed as leiomyoma on magnetic resonance (MR) images, was disclosed after focused ultrasound surgery (FUS). The tumor did not display high signal intensity either T1- or T2-weighted images the patient9s first visit. Four months thereafter, revealed a area within tumor, while T1-weighted showed low intensity. Six FUS, nonperfused volume calculated meglumine gadoterate-enhanced decreased markedly and an intermediate in circular appeared to be atypically increasing volume. After laparoscopic myomectomy, this uterine leiomyosarcoma coexistent with leiomyoma. early stages of are clinically difficult diagnose; therefore, both careful monitoring during FUS close follow-up procedure vital.
