title: F-18 FDG PET-CT imaging in gastric sarcoma.
abstract: We report the F-18 fluorodeozyglucose positron emission tomography computed tomography appearance of a biopsy-proven primary gastric sarcoma in a 24-year-old man who presented with early satiety, dyspepsia, and weight loss. Gastric sarcoma is a rare form of malignancy constituting approximately 0.3% to 8% of malignant soft tissue tumors of the stomach. The tumor appears as an ill-defined heterogeneous mass protruding off the lesser curvature of the stomach on computed tomography with central photopenia and peripheral intense uptake on positron emission tomography images.
