FDG PET/CT Imaging of Severe Polymyalgia Rheumatica.

A 68-year-old woman was referred for an 18F-FDG PET/CT for evaluation of arthralgia and raised inflammatory markers, which demonstrated intense FDG activity (SUVmax, 25.5) at numerous periarticular and extra-articular sites including the cervical and lumbar interspinous bursae, lumbar facet joints, bilateral ischial tuberosities, and greater trochanters and the aorta consistent with active polymyalgia rheumatica.
