Arthrograms of the shoulder were evaluated in 10 patients with rheumatoid arthritis. The arthrographic findings common to all joints consisted of nodular filling defects, irregular capsular attachments, bursal filling defects and visualized lymphatic drainage. Findings unique to the shoulder joint consisted of rotator cuff tear, frozen shoulder, and biceps sheath dilatation. Since the agents used to treat patients with rheumatoid arthritis have profound side effects, it is important to exclude an associated rotator cuff tear and/or confirm the presence of glenohumeral rheumatoid involvement.
