abstract: Ectopic pancreas is a rare congenital disorder characterized by the presence of the normal pancreatic tissue located outside the pancreas. The heterotopic pancreatic tissue in the mesentery of the jejunum is an entity that is seen very rarely. It is often found incidentally at different sites in the gastrointestinal (GI) tract. Although it is usually a silent anomaly, an ectopic pancreas may become clinically evident when complicated by inflammation, bleeding, obstruction or malignant transformation. However, the development of clinical symptoms depends on the size, location, and pathological changes similar to those observed in the case of the normal pancreas. Surgery is not indicated unless complications occur, so diagnosis is very important for prevention of unnecessary surgery. We present a case that had the ectopic pancreatic tissue in the mesentery of the jejunum. We show the computed tomography imaging findings of this patient. The presented case report demonstrated that heterotopic pancreas should always be considered in the differential diagnosis of gastric tumours.Keywords:ectopic heterotopic pancreas, jejunum, mesentery.
