Duplication duodénale non communicante, à propos d’un cas

Abstract

Duodenal duplication, belonging to the large group of digestive duplications, is a rare congenital malformation accounting for approximately 5% of all gastrointestinal duplications. Several theories have been proposed to explain the embryological basis of gastrointestinal tract duplications. However, no single hypothesis can explain all duplications. They are generally non-communicating spherical cysts located along the first and second parts of the duodenum, on the mesenteric side of the anterior wall. Communicating tubular forms are rare and most often asymptomatic. We report the case of an isolated duodenal duplication discovered incidentally in a 5-month-old infant admitted with a febrile respiratory condition and no major digestive disorders. The diagnosis was suggested by typical imaging findings.
