Gastrointestinal manifestations of amyloidosis: a case of diverticular perforation.

Amyloidosis is an intriguing disorder. Its clinical presentation usually rests on the organ(s) infiltrated with the amyloid. We report a patient who presented with peritonitis secondary to a perforated large jejunal diverticulum and multiple small bowel diverticula. We believe the diverticula were a direct result of primary amyloid infiltration of the intestine in the antimesenteric location. This is the first reported case of small bowel diverticula caused by amyloidosis.
