Giant ovarian leiomyoma as a rare cause of acute abdomen and hydronephrosis.

Abstract

Leiomyoma of the ovary is rare, usually small, and rarely induces serious symptoms. We report a case of a leiomyoma of the ovary that weighed 11.65 kg and led to acute abdomen and bilateral hydronephrosis. To our knowledge, this complication has not been described previously. Transabdominal sonography and computed tomography scan did not identify tumor type or origin. We performed a total abdominal hysterectomy and bilateral salpingo-oophorectomy. Abdominal symptoms and defects in urinary function disappeared completely after surgery. In very few cases, benign leiomyoma of the ovary may cause giant pelvic masses and peritoneal irritation.
