Abstract

A 79-year-old man presented with progressive respiratory distress. CT revealed the smooth thickening of airway walls, thyroid cartilage, cricoid cartilage, and costal cartilage. 18F-FDG uptake was observed in nasal, thyroid, cricoid, and costal cartilage on PET/CT. Biopsy was performed on costal cartilage and the histology observed was consistent with relapsing polychondritis (RPC). FDG-PET/CT is useful for the diagnosis of RPC and selection of biopsy sites.
