Pain and weakness after a fall. Question of rotator cuff tear. ROTATOR CUFF: There is a full thickness insertional tear involving the supraspinatus tendon with minimal retraction. We estimate the tear to measure just under 2 cm in the AP dimension. Increased signal intensity within the distal supraspinatus suggests mild tendinosis and fraying. The supraspinatus muscle appears normal. Small cysts in the lateral aspect of the humeral head is likely related to overlying rotator cuff pathology. There is also a small linear tear of the infraspinous tendon that appears to predominantly involve the undersurface fibers although it may extend to the bursal surface fibers as well without any retraction. The infraspinatus muscle appears normal. Thickening of the subscapularis tendon with intrasubstance signal distally likely represents tendinosis or perhaps interstitial tearing. The subscapularis muscle appears normal. The teres minor muscle/tendon appears normal.SUPRASPINATUS OUTLET: There is an os acromiale with mild osteoarthritis of the acromioclavicular joint. A small amount of fluid in the subacromial/subdeltoid bursa contains small foci of intermediate signal intensity presumably reflecting debris.GLENOHUMERAL JOINT AND GLENOID LABRUM: Glenohumeral alignment is within normal limits. Evaluation of the glenoid labrum is limited due to lack of intra-articular contrast; however, intermediate signal intensity throughout much of the labrum suggests degenerative tearing. There appears to be a small paralabral cyst along the posteroinferior aspect of the labrum.BICEPS TENDON: The tendon of the long head of the biceps appears intact.
