A 55-year-old female with unremarkable medical history experienced severe abdominal pain with left-sided tenderness and minimally elevated serum lipase. Multiplanar CT images showed collapsed gastric antrum with moderately thickened, stratified wall (*) and enhancing mucosa (thin arrows). Additionally, inflammatory hyperattenuation of surrounding and infrahepatic fat planes (+) reinforced suspicion of acute PUD. The subtle, small-sized mucosal defect with centimetric outpouching (arrows in c, d) corresponded to endoscopic finding (image in inset d) of posterior prepyloric ulcer with oedematous margins and fibrinous crater. The patient received medical therapy with continuous PPI infusion
