A Case of Lipoma of Terminal Ileum Causing Intussusception of the Transverse Colon

Intestinal intussusception is rare in adults. Intestinal intussusception is distinct from pediatric intussusception in that an identifiable leading lesion alters normal bowel peristalsis and forms the leading edge of the intussusceptum. The occurrence of lipomas is most common in the colon, followed by the small intestine, and then the stomach. Large lipomas may be associated with complications, such as intussusception or intestinal hemorrhage. In this case, a 77-year-old man was admitted to the hospital with a 10-day history of intermittent abdominal cramping. Computed tomography showed an intussusception of the transverse colon due to a primary mass with a dominant fatty density. The patient's obstructive symptoms resolved after colonoscopic reduction. Colonoscopy plays a useful role in the diagnosis and management of intussusception. The clinical, radiographic, and endoscopic findings are described herein with a brief review of the pertinent literature.
