[Intraluminal duodenal diverticulum. An unusual duodenal image. Apropos of 3 cases].

A rarely observed digestive tract disorder, an intraluminal duodenal diverticulum is usually discovered during the course of a barium gastroduodenal follow-through examination. Radiological appearances are characteristic: intraluminal globular opaque image surrounded by a clear border. Clinical signs are absent or non-specific, and surgery is rarely indicated, except when the lesions are poorly tolerated or complications develop.
