Right There are multiple foci of metallic susceptibility at the level of the acromioclavicular joint relating to prior surgery.ROTATOR CUFF: There is a massive tear of the rotator cuff including complete tears of the supra and infraspinatus tendons with retraction to the level of the glenohumeral joint. There is severe fatty atrophy of the infraspinatus muscle with moderate to severe fatty atrophy of the supraspinatus muscle. There is complete or near complete full-thickness tearing of the subscapularis muscle with retraction of most of the fibers to the level of the inferior glenoid. There is severe fatty atrophy of the subscapularis muscle. There is profound fatty atrophy of the teres minor muscle although the tendon itself appears to extend to the greater tuberosity.SUPRASPINATUS OUTLET: There is deformity of the distal clavicle and acromion indicating prior surgery. There is fluid within the subacromial subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: The humeral head is high riding. There is moderate osteoarthritis of the glenohumeral articulation with loss of the articular cartilage along the superomedial aspect of the humeral head. There is a moderate effusion with thickening of the synovium and a numerous small foci of debris within the joint. There is degeneration and degenerative tearing of the labrum, particularly superiorly.BICEPS TENDON: The intra-articular long head portion of the biceps tendon is not visualized, likely secondary to tearing.
Massive rotator cuff tear with profound associated muscle atrophy. Additional findings are described above.
