Ectopic Pancreas in the Duodenojejunal Flexure-Computed Tomographic and Endoscopic Ultrasonographic Images.

ABSTRACT

Ectopic pancreas is a rare entity where the pancreatic tissue has no anatomic and vascular contact with the main body of the pancreas and has its own duct system and vascular supply. A detailed clinical report with contrast-enhanced computed tomography (CT) and endoscopic ultrasonography (EUS) imaging findings of a 40-year-old male came with vague symptoms. CT showed a well-defined homogeneously enhancing mass lesion in the duodenojejunal (DJ) flexure. EUS revealed a well-defined hypoechoic mass lesion in the submucosal layer of the DJ flexure. Surgical resection of the mass was performed, and histopathological examination of specimen confirmed the pancreatic tissues. Here, we have described the CT and EUS imaging features which can help to differentiate the ectopic pancreas from the gastrointestinal submucosal tumours.
