Intraluminal duodenal diverticulum. Report of a case diagnosed by endoscopy.

Intraluminal diverticulum of the duodenum is a very rare congenital anomaly arising in the second part of the duodenum in close relation to the papilla of Vater. 39 cases have been reported in our available literature. The clinical symptoms and signs are nonspecific, and characteristically the preoperative diagnosis has in all cases been based on the roentgenographic appearance of the lesion. In this paper we present a case diagnosed by duodenoscopy, the radiological studies including hypotonic duodenography revealing no pathology.
