[Duodenal duplication: pathologic anatomy and embryogenesis. Case report in an adult]. / Duplication duodénale: anatomie pathologique et embryogenèse. A propos d'un cas chez l'adulte.

Duodenal duplication is a rare congenital entity and less than 100 cases have thus far been reported in the literature. This was first described by Sanger in 1880. By definition, they are located in or adjacent to the wall part of the gastrointestinal tract, have smooth muscle in 2 layers and are lined by alimentary tract mucosa. With the case report of a 18 year-old patient with pancreatitis, we expose modern imaging procedure and surgical management. Although the exact etiology of enteric duplications is not known, the two main hypothesis are dysembryogenesis and dysorganogenesis.
