A 56-year-old female patient who had involuntary weight loss underwent 18F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) for detection of malignancy. The scan revealed non-metabolic soft tissue density in the posterior wall of the stomach requiring endoscopy. Endoscopical examination was performed 9 days after PET/CT and cascade stomach was detected. Cascade stomach is a rare entity that can be diagnosed by radiographic barium evaluations and endoscopy, the appearance on CT is largely incidental and CT has rarely been relied on for the diagnosis. We present this incidental case of cascade stomach on PET/CT to be familiar with the appearance.
