Intraluminal duodenal diverticulum causing pancreatitis in a patient with a polysplenia syndrome.

Abstract

A 19-year-old female had recurrent bouts of pancreatitis. At endoscopy a mucosa-covered mass lesion was seen in the duodenum. A double-contrast examination of the stomach and duodenum showed an intraluminal duodenal diverticulum (IDD). Also an inversed abdominal situs and a midgut malrotation were noted. Computed tomography revealed evidence of a polysplenia syndrome. Although this syndrome is associated with various gastrointestinal abnormalities, its combination with an IDD does not seem to have been reported previously. After surgical removal of the IDD the patient has not had any further attacks of pancreatitis.
