Laparoscopic retrieval of a peritoneal mouse

Abstract

A 67-year-old Caucasian male was referred by the urology service with a history of incomplete bowel emptying. He complained of tenesmus. MRI scan suggested a leiomyoma lying anterior to the rectum. He underwent examination under anaesthesia and attempted endorectal ultrasound and biopsy. However, the lesion seemed to migrate cranially and was impalpable. At laparoscopy, amobile, unattached, 5.5 x 5 x 3.5, cream-coloured 'egg was retrieved fromthe retrovesical space.Histology confirmed a hyalinised fibrocollagenous lesion lined with mesothelium. A comprehensive review of the literature is presented. Copyright © 2010 Dara O. Kavanagh et al.
