Jejunal intussusception due to an atypical lipomatous tumor: a rare case report

Abstract

Intussusception in adults is rare, and the clinical symptoms of intussusception are subtle, making the diagnosis quite challenging. Gastrointestinal lipomas are rare benign tumors and are essentially adipose growths, most frequently found within the small intestine wall or mesentery. Limited up-to-date evidence exists regarding such lipomas. Intussusception due to a gastrointestinal lipoma constitutes an infrequent clinical entity, and the diagnosis of duodenal lipoma mainly depends on endoscopy examination, supplemented by computed tomography and magnetic resonance imaging. The present report describes a case of jejunal intussusception in an adult with a history of intermittent colicky abdominal pain located in the left upper quadrant over the last month. Contrast-enhanced computed tomography of the abdomen showed the typical target sign of a small intestinal intussusception along the left upper quadrant and a well-defined, low-density tumor in the intussusception. Exploratory laparotomy revealed jejuno-jejunal intussusception secondary to a lipoma, which was successfully treated with segmental intestinal resection.

A rare presentation of retroperitoneal liposarcoma presented with jejunal intussusception: An interesting radiological findings

“…Atypical lipomatous tumors and well-differentiated liposarcoma have similar morphological and genomics and mostly occur in the retroperitoneum or lower trunk [ 4 , 5 ]. There are not many cases reported on the jejunal intussusception secondary to an atypical lipomatous tumor except for only 2-3% of cases [ 6 ]. Most of the cases described have no concurrent multifocal retroperitoneal and intraperitoneal well-differentiated liposarcoma even though both are classified as intermediate adipocytic tumors.…”

Intussusception Related to Small Intestinal Lipomas: A Case Report and Review of the Literature

“…Small intestinal tumors account for only 1%–2% of all GI tumors, of which approximately 30% are benign lesions ( 7 ). Small intestinal lipomas account for 2.6% of all benign GI tumors ( 8 ). Lipomas tend to occur in the subcutaneous tissue and less frequently in the GI tract.…”
