What is the F-18 FDG PET-CT appearance of primary gastric sarcoma?
F-18 FDG PET-CT imaging of primary gastric sarcoma demonstrates an ill-defined heterogeneous mass with central photopenia and peripheral intense uptake.
Offers preliminary FDG PET-CT description in gastric sarcoma; leaves open diagnostic specificity and generalizability.
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.

Gamble et al. (2009) conducted a case report in Gastric Sarcoma (n=1). F-18 FDG PET-CT Imaging was evaluated on Imaging appearance. F-18 FDG PET-CT imaging of primary gastric sarcoma demonstrated an ill-defined heterogeneous mass with central photopenia and peripheral intense uptake.
