F-18 fluoro-2-deoxyglucose (F-18 FDG) positron emission tomography with computed tomography (PET/CT) is increasingly being used in the diagnosis of inflammatory disorders. We present a case of giant cell arteritis and polymyalgia rheumatica in a 64-year-old woman, identified on F-18 FDG PET/CT scanning during workup for an unknown primary tumor. This case highlights the importance of metabolic imaging in the assessment of extent and activity of large vessel vasculitis and related conditions.
