Abstract
Disseminated peritoneal leiomyomatosis (DPL) is an unusual extrauterine form of leiomyoma that has been found to coexist with its intrauterine counterpart in individuals who have previously undergone laparoscopic myomectomy. The presence of extrauterine masses with the density of smooth muscle on CT imaging and/or with a low signal intensity similar to that of smooth muscle on T (2) weighted MRI in a patient presenting with associated intrauterine leiomyoma and/or a history of previous laparoscopic myomectomy suggests the possibility of DPL. Imaging studies help in diagnosing and delineating the location and extent of the lesion and also follow-up the masses to look for sarcomatous transformation. Here we report the case of a 43-year-old female who presented initially with right lower quadrant pain. Her CT scan and MRI demonstrated a fundal fibroid with multiple intraperitoneal soft tissue masses of similar appearance and contrast enhancement in the sigmoid mesocolon, the left paracolic gutter and adjacent to the ascending colon. The suspected diagnosis of DPL was confirmed during abdominal hysterectomy, bilateral salphingo-oophorectomy and excision of peritoneal masses.
