Case Discussion
Case of duodenal diverticulum with a lipoma (incidental findings in this case).
Duodenal diverticula are very common, found in up to 23% of asymptomatic patients. Potential complications are rare and include duodenal diverticulitis, hemorrhage, perforation, abscess formation and biliary duct obstruction ( Lemmel syndrome).
Gastrointestinal tract lipomas are not uncommon and can be found anywhere along the entire length of the gastrointestinal tract. Usually asymptomatic and found incidentally, the pedunculated form can occasionally present as the leading point of an intussusception.
