A case of gouty arthritis to tophi on 18F-FDG PET/CT imaging.

We report a case of gouty arthritis with tophi that was evaluated using 18F-fluorodeoxyglucose (FDG) positron emission tomography. A 77-year-old man with a history of gouty attacks was admitted with severe polyarticular pain and fever. 18F-FDG positron emission tomography/CT demonstrated focal uptake at multiple joints, including the juxta-articular soft-tissue-density masses of the elbows, and the bases of bilateral large toes. Gouty arthritis should be considered with focal 18F-FDG uptake in juxta-articular soft-tissue-density masses (tophi) with or without associated erosions.
