Core Tip
Core tip: Duodenal intussusception is usually impossible except in cases of malrotational abnormality. Some cases of duodenal intussusception without malrotational abnormalities have been reported, but it is unclear whether this phenomenon is true intussusception or simple mucosal prolapse. We present a case of true duodenal intussusception secondary to ampullary adenoma without malrotational abnormality. Computed tomography showed a tumor as the lead point and retroperitoneal structure, including the head of the pancreas and fat, invaginating beyond the duodenojejunal flexure to the jejunum. This phenomenon was associated with mucosal prolapse.
