Polymyalgia rheumatica (PMR) is an inflammatory rheumatic condition characterized by generalized pain and morning stiffness in the shoulders, hip girdle, and neck. Since the pathogenesis of PMR is still uncertain, the diagnosis of PMR depends on clinical features. There have been several studies regarding radiological tools for the diagnosis of PMR. Recent studies using 18-FDG-PET showed bursitis, synovitis, uptake in the spinous process and asymptomatic large-vessel vasculitis in PMR patients. However, there was no report on the efficacy of 18-FDG-PET for diagnosis of PMR in Korea. Here, we are first reporting a case of a Korean patient with PMR, who had radiological findings including bursitis, synovitis, uptake in the spinous process and asymptomatic large-vessel vasculitis on 18-FDG-PET/CT.
