Reason: Evaluate for rotator cuff tear versus labral tear (arthrogram ordered with this order) History: persistent left shoulder pain and snapping ROTATOR CUFF: There is thickening and intermediate signal intensity within the supraspinatus indicating mild to moderate tendinosis. The supraspinatus and infraspinatus muscles and tendons appear intact. The subscapularis and teres minor muscles and tendons appear intact.SUPRASPINATUS OUTLET: No significant fluid is identified within the subacromial subdeltoid bursa. No intra-articular gadolinium is identified within the subacromial subdeltoid bursa. The acromioclavicular joint is unremarkable.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is anatomic. No full-thickness articular cartilage defects are identified. There is linear signal abnormality within the anterior superior labrum which fills with intra-articular gadolinium likely representing a normal variant sublabral recess. There is heterogeneity of the posterior superior glenoid labrum likely representing a combination of degeneration and degenerative tearing.BICEPS TENDON: The tendon along the biceps appears intact. ADDITIONAL
1. Degeneration/degenerative tearing of the posterior superior labrum. 2. Mild to moderate rotator cuff tendinosis without evidence of a full-thickness rotator cuff tear or retraction.
