43-year-old male with left shoulder pain and weakness. Evaluate for rotator cuff tear. ROTATOR CUFF: There is thickening and increased signal abnormality within the supraspinatus tendon consistent with moderate tendinosis. No full-thickness or near full-thickness tear is evident. There is interstitial tearing of the infraspinatus tendon. The supraspinatus and infraspinatus muscles appear intact. The subscapularis and teres minor muscle and tendon appear intact.SUPRASPINATUS OUTLET: Note is made of an os acromiale.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is a small glenohumeral joint effusion. Note is made of low signal abnormality within the fluid within the glenohumeral joint (image 12; series 4). There is fragmentation of the superior posterior glenoid labrum which is suspicious for degenerative labral tearing.BICEPS TENDON: There is a large amount of fluid within the tendon sheath of the long head of the biceps tendon. There is associated low signal intensity abnormality identified within the aforementioned fluid along the long head of the biceps tendon (image 10; series 4). ADDITIONAL
1. Findings suspicious for synovitis of the glenohumeral joint with associated tenosynovitis of the long head of the biceps tendon. 2. Interstitial tearing of the rotator cuff without evidence of near full-thickness or full-thickness rotator cuff tear.3. Os acromiale. 4. Fragmentation of the superior posterior glenoid labrum which is suspicious for degenerative labral tearing.
