61-year-old male with left shoulder pain. ROTATOR CUFF: There is a full-thickness tear of the posterior fibers of the supraspinatus tendon at the level of its insertion on the greater tuberosity measuring 11 mm in AP dimension. There is near full-thickness articular surface tearing of the anterior fibers of the infraspinatus at the level of its insertion on the greater tuberosity measuring approximately 15 mm in AP dimension. There is partial thickness undersurface tearing of the subscapularis tendon at the level of its insertion on the lesser tuberosity without significant retraction. Teres minor tendon appears intact. There is diffuse fatty atrophy of the teres minor muscle. No mass lesions are identified within the quadrilateral space. There is minimal fatty infiltration at the level of the myotendinous junction of the infraspinatus.SUPRASPINATUS OUTLET: There is a trace amount of fluid within the subacromial subdeltoid bursa. Mild degenerative changes affect the acromioclavicular joint with inferior osteophyte formation resulting in impression upon the superior fibers of the supraspinatus.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is anatomic. There is increased signal abnormality and heterogeneity of the superior and superior posterior glenoid labrum indicating degenerative tearing with extension into the biceps anchor.BICEPS TENDON: There is a longitudinal split tearing of the intra and extra articular portion of the long head of the biceps.ADDITIONAL
1. Full-thickness tearing of the rotator cuff as described above.2. Degenerative tearing of the glenoid labrum with extension into the biceps anchor.3. Longitudinal split tear of the long head of the biceps tendon.4. Degenerative osteoarthritic changes of the glenohumeral joint and acromioclavicular joint.
