Beware of a multi-fibroid uterus: The importance of ultrasound reporting in the early detection of uterine sarcomas.

Primary uterine malignancy masquerading as a benign leiomyoma is a rare yet devastating condition if missed on ultrasound. Although there are no current guidelines to aide in early ultrasound identification of these high-risk patients prior to histological analysis, certain imaging characteristics may heighten the suspicion of malignancy. Unfortunately, these atypical features are often not included in ultrasonographic reports resulting in delayed treatment and catastrophic consequences.
