To evaluate the performance of musculoskeletal ultrasound (US) in the initial assessment and follow up of patients over the age of 50 years presenting with recent onset bilateral shoulder pain.
US of shoulder and hips was performed in 89 patients with an initial diagnosis of new onset PMR, 117 control subjects with newly diagnosed conditions mimicking PMR presenting with recent onset of bilateral shoulder pain (includes 37 subjects with new onset rheumatoid arthritis (RA), 30 subjects with other shoulder conditions) and 21 controls without shoulder conditions. All subjects were >=50 years of age. US evaluations were performed using a standardized protocol developed as part of a 6-month prospective study and included assessment of subdeltoid bursitis, biceps tenosynovitis, glenohumeral or hip synovitis and trochanteric bursitis. A preceding training and standardization exercise of US operators at different sites in the study demonstrated very good intercenter comparability of results.
Patients with PMR were more likely to have abnormal US findings in the shoulder (particularly subdeltoid bursitis and biceps tenosynovitis), and somewhat more likely to have abnormal findings in the hips than control subjects as a group. PMR could not be distinguished from RA on the basis of US, but could be distinguished from non-RA shoulder conditions and subjects without shoulder conditions.
In this largest and first multicenter study of US in PMR, most subjects with PMR have abnormal findings on shoulder US. US had limited value in distinguishing PMR from RA, but had value in discriminating PMR from other conditions associated with shoulder pain. US of the shoulders and hips may have added value for diagnosis of PMR.
