Adult Ileocolic Intussusception Secondary to Cecal Lipoma: A Case Report.

Large intestinal intussusception is rare in adults. Among potential pathologic lead points for intussusception are lipomas, benign tumors very infrequently found in the large bowel. A 30-year-old woman presented to the emergency department with a chief complaint of generalized abdominal pain for two weeks. A computed tomography scan of her abdomen and pelvis showed an ileocolic intussusception with a lead point of 6.7 cm. The lead point appeared to be predominantly fat. A colonoscopy revealed a large, obstructing lesion in the transverse colon. The patient underwent exploratory laparotomy with a right hemicolectomy, and a pathologic diagnosis of a lipoma was made. The patient recovered from surgery without complications and returned to her normal diet three weeks after discharge. This case highlights an unusual and rare presentation of an ileocolic intussusception caused by a cecal lipoma acting as a lead point.
