title: Thin-section chest CT findings in polymyalgia rheumatica: a comparison between with and without rheumatoid arthritis.
abstract: We retrospectively compared the thin-section chest computed tomography (CT) findings between 25 patients of polymyalgia rheumatica (PMR) with rheumatoid arthritis (RA) and 29 patients of PMR without RA. PMR patients showed high-frequency CT abnormalities (68.5%) regardless of the association with RA. Ground-glass opacity (56% vs. 24%), traction bronchiectasis (44% vs. 3%), architectural distortion (32% vs. 0%), centrilobular nodules (32% vs. 7%), and honeycombing (20% vs. 0%) were significantly more common in the PMR with RA group than in the PMR without RA group (P<.01). PMR patients with RA have more increased prevalence of chest CT abnormalities than those without RA.
