61-year-old female with pain. Previous rotator cuff repair. The study is markedly suboptimal in quality due to metallic susceptibility artifact from the patient's suture anchors within the humeral head as well as patient motion artifact. Furthermore, the patient refused further imaging. ROTATOR CUFF: Anteriorly, the supraspinatus appears thinned which likely reflects partial thickness chronic attritional tearing or a full thickness tear, although we see no tendon retraction. More posteriorly, the supraspinatus tendon is of relatively normal thickness, although its insertion on the greater tuberosity cannot be assessed due to the aforementioned metallic susceptibility artifact. The bulk of the supraspinatus muscle appears decreased, although there is relatively little fatty infiltration. The visualized portions of the infraspinatus muscle and tendon appear normal, although its insertion cannot be assessed due to metallic susceptibility artifact. The teres minor muscle and tendon appear grossly intact. There is increased signal intensity within the superior fibers of the subscapularis suggesting partial thickness tearing, but we see no full-thickness tear. SUPRASPINATUS OUTLET: Mild to moderate osteoarthritis affects the acromioclavicular joint. There perhaps a trace amount of fluid within the subacromial subdeltoid bursa. GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is within normal limits. There is a small amount of fluid within the joint but no large effusion is evident. Given the aforementioned limitations, we see no labral tear. Mild osteoarthritis affects the glenohumeral joint. BICEPS TENDON: The extra-articular portion of the tendon of the long head of the biceps appears appropriately situated within the bicipital groove. The intra-articular portion is not well seen due to the aforementioned limitations.
Extremely limited evaluation of the right shoulder as described above which shows thinning of the anterior aspect of the supraspinatus tendon, but we cannot confirm or exclude a full-thickness tear. However, we see no frankly retracted tendon fibers. Other findings as described above. If further imaging evaluation is clinically warranted, CT arthrography may be considered.
