Abstract

<abstract> <title>Abstract</title> <p> <italic>Objectives.</italic> The purpose of this study is to evaluate magnetic resonance imaging (MRI) findings of the shoulder and hip joint in patients with polymyalgia rheumatica (PMR).</p> <p> <italic>Methods.</italic> MR images of a total of 25 PMR patients (23 shoulders and 6 hips), 43 rheumatoid arthritis (RA) patients (22 shoulders and 22 hips), and 50 control patients (25 shoulders and 25 hips) were examined. The following MRI findings were evaluated: In the shoulder, thickness and abnormalities of the supraspinatus tendon, effusion around the glenohumeral joint, subacromial-subdeltoid bursa, and the biceps tendon; In the hip, effusion around the acetabulofemoral joint, iliopsoas bursa, and trochanteric bursa. Periarticular soft-tissue edema and bone findings were also analyzed.</p> <p> <italic>Results.</italic> The supraspinatus tendon was significantly thicker in PMR patients than in RA patients and control patients (<italic>p</italic> < 0.05). Severe rotator cuff tendinopathy was frequently observed in PMR patients (<italic>p</italic> = 0.002). The scores for the amount of effusions (joint, bursa, and tendon sheath in the shoulder and bursa in the hip) were much higher in PMR patients (<italic>p</italic> < 0.05). Periarticular soft tissue edema was detected more frequently in PMR patients than in RA patients and control patients (<italic>p</italic> < 0.05).</p> <p> <italic>Conclusions.</italic> Thick supraspinatus tendon, severe rotator cuff tendinopathy, effusion around the joints, and periarticular soft tissue edema can be good indicators for the diagnosis of PMR.</p> </abstract>
