A 46-year-old woman complained of persistent abnormal vaginal bleeding over ten days. Her intrauterine device had been removed two years before. Soon after, she suffered from menorrhagia and metrorrhagia. An incidental finding of severe anemia was also noted. In this admission, our initial T2-weighted magnetic resonance imaging (MRI) revealed a well-demarcated mass pre­dominantly in the uterine cavity. The mass was depicted by an isointense signal relative to the myometrium on Tl-weighted images, high signal intensity on T2-weighted images, and slightly heterogeneous enhancement on post-contrast images. The patient refused surgery. After two years, follow-up MRI showed a pedunculated mass protruding into the upper third of the vagina with a stalk con­necting to the posterior wall of the uterine cavity, simulating submucosal myoma. Histological diagnosis was compatible with low­grade endometrial stromal sarcoma.
