An unusual case of gastric diverticulosis.

Gastric diverticula are usually single and most frequently occur in the juxta-cardiac region of the stomach. Prepyloric diverticula generally are rare, single, and usually acquired. We describe a patient with multiple prepyloric diverticula and pyloric stenosis diagnosed by upper gastrointestinal x-ray studies and endoscopy. To our knowledge, this association has not been reported previously.
