Double ileoileal intussusception caused by a giant polypoid mass of heterotopic pancreas in a child.
Heterotopic pancreatic tissue has been found in several abdominal and intrathoracic locations. In the ileum, it is a rare, usually asymptomatic, incidental finding. A unique case of a recurrent ileoileal intussusception in an 11-year-old girl is presented caused by a giant polypoid mass composed of ectopic pancreatic tissue that remained undetected during several diagnostic tests during two previous admissions and laparoscopic abdominal exploration.
