Acute colonic obstruction caused by intussusception and extrusion of a sigmoid lipoma through the anus after barium enema. Abdominal imaging. [Abdom Imaging] Journal article

Colonic lipomas are often asymptomatic, but large lipomas may produce abdominal pain, diarrhea, constipation, hemorrhage, and intussusception. We report a young woman with a colonic lipoma who presented as an acute abdominal emergency with total colonic obstruction and severe pain associated with intussusception and extrusion of the tumor through the anus. The case was interesting because of its presentation after a double-contrast barium enema and because of the patient's young age and the tumor's location on the left side of the colon.
