Congenital Diaphragm of the Descending Duodenum: Radiographic Demonstration of Such Lesion

Abstract
A case of a partially obstructing congenital intrinsic diaphragm in the descending duodenum in a 15-month-old male is reported. This uncommon lesion has been rarely diagnosed prior to surgery or autopsy. Radiographs are submitted on which the pre-operative diagnosis was accurately made. It is emphasized that these thin diaphragms are not palpable through the intact duodenal wall. The surgeon should open the bowel and inspect the area of suspicion. The presence of a congenital extrinsic band should not be held to contraindicate such inspection. The operation of choice is a duodenojejunostomy or a duodenoduodenostomy.
