Abstract

Gastric ulcer perforation usually results in panperitonitis, which requires surgical treatment. A peritoneal abscess also can occur with gastric ulcer perforation, but it is not a common complication of peptic ulcer disease. Here, we report a peritoneal abscess that mimicked a tumor and was caused by a gastric ulcer and provide a literature review. A 57-year-old woman was admitted to our hospital for evaluation of an abdominal mass found in another hospital, with no signs of infection. She underwent a left lobectomy of the liver due to choledocholithiasis. Abdominal computed tomography (CT) revealed a heterogeneous mass attached to the antrum of the stomach. At endoscopy, we confirmed that the gastric ulcer at the antrum of the stomach caused the abscess. After 4 weeks of antibiotics and proton pump inhibitor treatment, she was cured. In a patient with abdominal pain and a peritoneal abscess of unknown cause, the possibility of peptic ulcer perforation should be considered.
