Gastroduodenal artery aneurysm presenting as gastric outlet obstruction.

Abstract

A 30-year-old female with a history of acute biliary pancreatitis two months ago, presented with a four-week history of recurrent vomiting, occurring one to two hours after meals. The patientunderwent an endoscopy, showing a 3 cm mass arising from the posterior wall of the duodenal bulb impinging the pyloric opening (Fig. 1A), with overlying normal mucosa. In view of a suspected subepithelial lesion, an endoscopic ultrasound was performed, showing a 3.2 × 2.6 cm aneurysm (Long arrow, Fig. 1B) arising from the gastroduodenal artery (GDA) (Short arrow, Fig. 1B).
