title: Inflammatory myofibroblastic tumor mimicking gastric gastrointestinal stromal tumor on 18F-FDG PET/CT.
abstract: A 59-year-old man underwent abdominal CT for evaluation of weight loss and generalized weakness. A large mass protruding from the lesser curvature of the stomach suggestive of gastrointestinal stromal tumor was demonstrated. F-FDG PET/CT showed hypermetabolic activity in the gastric mass. Mass excision and wedge resection were performed, and the diagnosis of inflammatory myofibroblastic tumor was confirmed.
