Abstract

A 66-year-old man with background hypertension and type 2 diabetes presented with 1 month history of epigastric pain for investigation. Abdominal CT and MRI identified round homogeneously enhancing mass arising from the lesser curvature of the stomach. On 18 F-FDG PET/CT, the gastric mass demonstrated intense FDG uptake (SUV max , 9.6). The patient subsequently underwent partial gastrectomy, with pathological features and immunohistochemical patterns consistent with gastric schwannoma.
