RESUMEN

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.
