Primary gastric lymphoma (PGL) accounts for less than 4% of gastric neoplasms. 18F-FDG PET with simultaneously acquired CT (18F-FDG PET/CT) allows for staging and differentiation from other gastric cancers. Rapid diagnosis and staging are important because chemotherapeutic response is generally favorable. We describe a case of an 83-y-old woman with stage II1 PGL. 18F-FDG PET/CT can be helpful to differentiate various gastric masses and is an important factor in the staging of PGL.
