Does Any Imaging Method Allow Distinguishing Between Myoma and Sarcoma

Myomas are the most common benign tumors of the uterus and can be found in 77 % of all hysterectomies, whereas uterine sarcoma is a very rare disease with a poor prognosis. The clinical characteristics of uterine fibroids and sarcoma are often similar. A history of pelvic irradiation, lung metastases, and missing response to different fibroid treatments can give hints toward uterine sarcoma. A spectrum of MRI findings has been described, but there are no pathognomonic features on any imaging technique.
