Abstract

Perforation is a serious complication of peptic ulcer disease occurring in 5% of such patients. Occasionally, the perforation may be sealed off by the omentum or the adjacent organs. Sealed perforated ulcer with pseudotumor formation is very rarely encountered. Here we present a case of gastric pseudotumor induced by perforation of a peptic ulcer. The imaging features in a barium sulfate study and computed tomography mimic an intramural tumor of the stomach.
