Intussusception-induced acute abdomin caused by a giant lipoma in the transverse colon: a rare case report.

Abstract

The authors present a case of a 48-year-old male who presented to the emergency department suffering from severe abdominal pain. Following examination and investigations, a giant lipoma (GL) in the transverse colon was identified via ultrasound which showed the classical "target sign" Intussusception among adults is unusual as it accounts for only 1% of bowel obstruction cases. Being colo-colonic makes it even more unlikely since it occurs only in 17% of intestinal obstruction cases. GLs exceeding 5cm in size can present with a variety of symptoms. Intussusception is an uncommon presentation of a GL. Preoperative diagnosis of GL-induced intussusception is highly improbable and surgical resection is the treatment of choice. Despite the dominance of the asymptomatic presentation of lipomas, considering its diagnosis in the case of an intussusception-induced acute abdomen should cross physicians' minds.
