18F-2-Fluoro-2-deoxyglucose (FDG) is the workhorse of oncological PET/CT departments. Its role in staging, restaging, and response assessment of various cancers is already established. But FDG is a marker of glycolysis and, thus, is neither specific for malignancy nor for a particular tumor. Its accumulation can be seen in benign process which may be difficult to differentiate from a neoplastic etiology. It is imperative that nuclear physicians and radiologists know about these FDG-avid benign pathologies and few FDG-negative malignant etiologies, which may confound correct interpretation in PET/CT reporting.
