Multiple uterine angioleiomyomas in a woman presenting with severe menorrhagia

Angioleiomyoma is a rare benign neoplasm that originates from smooth muscle cells and contains thick-walled vessels. There were only five cases of uterine angioleiomyoma reported in the available English literatures. We present here the unique computed tomography finding in a patient with multiple uterine angioleiomyomas causing severe menorrhagia.A 50-year-old, nulligravid woman consulted us with the complaint of menorrhagia for 3 years and progressively palpable lower abdominal mass for a half year. Laboratory findings were all within normal limits except lower hemoglobin concentration (6.2 g/dl). An abdomino-pelvic computed tomography (CT) showed that a huge 30-cm heterogeneously multilobulate mass with solid and laminated configuration, with cystic and multiseptal contents was found in left lower abdomen and pelvic cavity. At laparotomy, the area beneath the left broad ligament was filled with a well-encapsulated, elastic, ovoid, and lobulate mass that connected to the uterus and measured up to 20 cm in greatest diameter. The uterus was composed of a huge intramural tumor and measured 28 x 21 x 12 cm. The uterus and huge subserosal tumor were resected completely and a frozen section was obtained. The final histopathologic diagnosis was angioleiomyoma, a definitely benign soft tissue tumor. Eighteen months after surgery there was no recurrence.Uterine angioleiomyoma should be considered when prominent tortuous vascular-like enhancing structures are noted on CT examination of a well-demarcated soft tissue mass arising from the uterus in pelvis. Either angiomyomectomy with tumor-free margins or hysterectomy proved to be an effective treatment in these cases, and resulted in a good recovery and a satisfactory outcome.
