Uterine leiomyomas affect 20 to 30% of women older than 35 years. Extrauterine leiomyomas are rarer, and they present a greater diagnostic challenge. These histologically benign leiomyomas occasionally occur with unusual growth patterns or in unusual locations which make their identification more challenging both clinically and radiologically. Unusual growth patterns may be seen, including benign metastasizing leiomyoma, disseminated peritoneal leiomyomatosis, intravenous leiomyomatosis, parasitic leiomyoma, and retroperitoneal growth. Diffuse peritoneal leiomyomatosis manifests as innumerable peritoneal nodules resembling those in peritoneal carcinomatosis. Parasitic leiomyoma and retroperitoneal leiomyomatosis usually manifest as single or multiple pelvic or retroperitoneal masses. Retroperitoneal growth is yet another unusual growth pattern of leiomyomas. Multiple leiomyomatous masses are usually seen in the pelvic retroperitoneum in women with a concurrent uterine leiomyoma or a history of uterine leiomyoma. Rarely, the extrauterine masses may extend to the upper retroperitoneum, as high as the level of the renal hilum. Occasionally, leiomyomas become adherent to surrounding structures (e.g., broad ligament, omentum, or retroperitoneal connective tissue), develop an auxiliary blood supply, and lose their original attachment to the uterus, hence becoming “parasitic.” We are presenting a case of extrauterine leiomyoma, which was operated for laparoscopic myomectomy for huge cervical leiomyoma 4 years back but was converted to an abdominal myomectomy.
