Abstract

Annular pancreas is a developmental anomaly that can be associated with other conditions such as Down syndrome, duodenal atresia, and Hirschsprung disease. A band of pancreatic tissue, in continuity with the pancreatic head, completely or incompletely encircles the descending duodenum, sometimes assuming a "crocodile jaw" configuration. We present the case of an adult who presented with epigastric pain and vomiting and was found to have annular pancreas.
