Double jejunal intussusception in an adult with chronic subileus due to a giant lipoma: a case report.

We present a case of a 40-year-old male with a clinical history of intermittent intestinal occlusion, abdominal pain and moderate weight loss. Physical examination and laboratory tests were unremarkable. Diagnostic imaging including CT, MR and small-bowel barium X-rays provided evidence of a jejunal lesion of an unknown nature downstream of the ligament of Treitz. Only at surgery was it possible to identify a double intussusception due to a giant stalked polyp which the histological examination revealed to be a submucosal lipoma.
