An ectopic pancreas is an anatomical abnormality in which pancreatic tissue has grown outside its normal location and without vascular or other anatomical connections to the pancreas.[2] It is a disease which is congenital[2] and is also known as heterotopic, accessory, or aberrant pancreas.[3]

Signs and symptoms

Often, heterotopic pancreas is

incidental finding
on imaging studies performed for an unrelated reason.

Ectopic pancreatic tissue may occur anywhere in the abdominal cavity, though more than 90 percent are found in the stomach, duodenum, or jejunum.[1] Rarely, pancreatic heterotopic tissue may be found in the colon, spleen or liver.[1]

Diagnosis

Treatment

If no symptoms are present, then treatment is not necessary. When symptoms are present, treatment consists of surgical resection.[1]

Epidemiology

The incidence of heterotopic pancreas is relatively low.[1]
