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.
