Since the patient initially presented with vague abdominal complaints and an initial KUB (not shown) was interpreted as normal, he underwent abdominal CT scanning. The CT findings, highly suspicious for a bleeding duodenal ulcer, were validated on gastroduodenoscopy. DSA was performed where, even though there was no demonstration of active bleeding, the gastroduodenal artery (GDA) was correctly surmised to be the culprit artery since it supplies the proximal duodenum.

The gallbladder fundal wall thickening turned out to be adenomyomatosis.
