Isolated Heterotopic Pancreas in Ileoileal Intussusception

A heterotopic pancreas is a developmental anomaly defined as pancreatic tissue found on ectopic sites without contiguity with the main pancreas.(1) A heterotopic pancreas of the ileum is rare and is usually found in a Meckel diverticulum, which may cause intussusception in childhood.(2,3) An isolated heterotopic pancreas as the lead point of intussusception is extremely rare.(1) Furthermore, to our best knowledge, sonographic features of an isolated heterotopic pancreas in ileoileal intussusception have not been reported. We report a case of an isolated heterotopic pancreas in a 6-month-old boy with ileoileal intussusception and describe the sonographic features that cot-related with the histopathologic findings.
