Duodenal duplication with pancreas bifidum--a case report.

Duodenal duplications constitute less than five percent of gastrointestinal duplications. Rarely, enteric duplication cysts are found in an intra- or juxtapancreatic position with or without connection to the pancreatic duct. Complete pancreaticoduodenal duplication is even less common, although there is a close relationship in the development of the two organs. We report here the case of a child with a paraduodenal cystic lesion, followed up since infancy, which turned out to be duodenal duplication cyst with a connection to Wirsung's duct of the ventral pancreas.
