What is the cause of this sigmoid stricture in this 43yr old lady with a
3 year history of cyclical lower abdominal pain?
Abstract
CT Colonography was performed after difficulty passing the stricture at
colonoscopy. On imaging, the stricture was concerning for neoplasm (Fig
1). The patient underwent a segmental colectomy with histological
analysis of the stricture demonstrating endometrial tissue(Fig 2.). The
cause of abdominal pain was therefore secondary to extrapelvic
endometriosis.
