50-year-old male with right shoulder pain. Evaluate for bicipital tendinopathy. ROTATOR CUFF: Note is made of a partial-thickness undersurface tear of the supraspinatus tendon at the level of its insertion on the greater tuberosity, involving greater than 50% of the tendon width, measuring approximately 2.1 cm in the AP dimension. There is associated delamination of the undersurface fibers with approximately 2 cm of retraction. The supraspinatus muscle appears intact. There is partial thickness undersurface tearing of the anterior fibers of the infraspinatus at the level of its insertion on the greater tuberosity. There is interstitial tearing of the infraspinatus tendon at the level of the myotendinous junction. There is thickening and intermediate signal abnormality within the infraspinatus indicating mild tendinosis. The teres minor and subscapularis tendons and muscles appear intact.SUPRASPINATUS OUTLET: There is no significant fluid within the subacromial subdeltoid bursa. Mild to moderate degenerative changes affect the acromioclavicular joint with inferior osteophyte formation.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is anatomic. There is heterogeneity and increased signal abnormality within the anterior inferior glenoid labrum indicating degenerative tearing within the limitations of a non arthrogram study. There is also increased signal abnormality traversing the superior glenoid labrum indicating degenerative tearing. There is no signal abnormality extending into the biceps anchor within the limitations of a non arthrogram study.BICEPS TENDON: The tendon of the long head of the biceps appears intact. There is thickening and intermediate signal abnormality within the intra-articular portion of the long head of the biceps indicating mild to moderate tendinosis. There is fluid within the tendon sheath of the long head of the biceps which likely represents fluid extension from the glenohumeral joint versus a very mild tenosynovitis.ADDITIONAL
1. Near full-thickness undersurface tear of these rotator cuff with retraction as described above.2. Tendinosis of the long head of the biceps tendon.3. Degenerative tearing of the glenoid labrum.
