Large focal collection of feces in the sigmoid without signs of obstruction or diverticular disease but with local wall thickening in the sigmoid and signs of a local perforation by way of free intraperitoneal gas (arrow).

Case Discussion

Stercoral ulcer is thought to be an ischemic phenomenon due to the pressure effect of a large, hard fecal bolus on the bowel wall, i.e. pressure necrosis. If prolonged and severe, the colon can perforate.
