47-year-old male with history of shoulder pain. Evaluate for rotator cuff tear. ROTATOR CUFF: There is thickening and increased signal abnormality of the supraspinatus tendon at its insertion with a longitudinal linear component at the two o'clock position (posterior/superior) extending through most of the tendon compatible with a full-thickness longitudinal tear. The supraspinatus muscle is unremarkable. There is no evidence of tendon retraction. Mild tendinosis affects the remainder of the rotator cuff.SUPRASPINATUS OUTLET: There is a small amount of fluid within the acromioclavicular articulation. There is no fluid within the subacromial or subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: The anterior and superior glenoid labrum appear attenuated and of mildly increased signal intensity likely representing degeneration and probable attritional tearing. Bone marrow signal intensity is unremarkable.BICEPS TENDON: No significant abnormality noted. ADDITIONAL
Full-thickness longitudinal split tear of the supraspinatus tendon near its insertion in the background of moderate tendinosis. Other findings as above.
