Duodenal lipoma causing intussusception

Abstract

Duodenal intussusception and duodenal lipomas are both rare clinical entities. A case of duodenal intussusception caused by a lipoma is presented. The diagnosis of lipoma may be made endoscopically and radiographically using both upper gastrointestinal series and computed tomographic scan. Intussusception in the duodenum may be partial and cause minimal symptoms, but it has distinctive roentgenographic findings. The treatment of symptomatic lipomas may be endoscopic removal, using snare and cautery, or local excision via duodenotomy. Intussusceptions must be reduced operatively.
