Rotator cuff injury in past. Patient presents with pain and weakness. ROTATOR CUFF: There is a near-complete to complete tear of the supraspinatus tendon with retraction of the majority of the tendon to the level of the glenohumeral joint although a few anterior fibers may extend to the greater tuberosity.There is a complete tear of the infraspinatus tendon with similar retraction to the level of the glenohumeral joint.There is severe fatty atrophy of the supraspinatus and infraspinatus muscles.The teres minor tendon appears intact. There is moderate fatty atrophy of the teres minor muscle.There is thickening and increased signal intensity of the subscapularis tendon indicating moderate tendinosis. There is mild fatty atrophy of the subscapularis muscle.SUPRASPINATUS OUTLET: Moderate osteoarthritis affects the acromioclavicular joint. There is a small amount of fluid in the subacromial subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is mild to moderate osteoarthritis of the glenohumeral joint which has progressed slightly when compared to the prior study. The humeral head is high riding due to the chronic rotator cuff tear.There is a tear of the superior labrum extending down the posterior labrum that has perhaps progressed slightly when compared to the prior study.Increased signal intensity within the superior aspect of the anterior labrum likely also represents additional degenerative tearing.Multiple cysts are again noted within the greater tuberosity.There is a small glenohumeral joint effusion containing foci of intermediate signal intensity likely reflecting synovitis and cartilaginous debris. BICEPS TENDON: The tendon of the long head of the biceps is visualized within the inferior aspect of the bicipital groove, however it is not well visualized within the superior aspect of the groove or within the rotator interval, suspicious for a proximal tear. This appears similar to that seen on the prior study.
1. Tears of the supraspinatus and infraspinatus tendons as described above with further tendinous retraction as well as atrophy of the muscles. Other rotator cuff findings as described above2. Acromioclavicular joint osteoarthritis.3. Slight progression of glenohumeral joint osteoarthritis with labral tearing.4. Findings suggestive of proximal rupture of the tendon of the long head of the biceps.
