Polymyalgia rheumatica as the manifestation of unclassified aortitis

Abstract

Polymyalgia rheumatica (PMR) frequently occurs with giant cell arteritis (GCA). We report here two cases of PMR with aortitis in the absence of diminished pulse and manifestations related to GCA. Contrasted CT, MR angiography, and F-18-deoxyglucose positron emission tomography showed aortitis without stenosis that is not classified into any of large vasculitides. It should be acknowledged that aortitis might present as PMR and imaging studies are recommended.
