Combined ileal heterotopic pancreatic and gastric tissues causing ileocolic intussusception in an infant.

Pathological intussusception is rare in infancy with Meckel's diverticulum being the most common lesion. Isolated heterotopic pancreatic tissue in the serosa of the ileum causing intussusception is extremely rare. We report a case of ileal heterotopic pancreatic tissue associated with ectopic gastric mucosa causing ileocolic intussusception in an infant, with review of the literature.
