65-year-old female patient status post motor vehicle collision with rotator cuff injury. ROTATOR CUFF: There is a full-thickness near complete tear of the supraspinatus tendon with nearly 1.5 cm of proximal retraction of the torn fibers. This tear measures approximately 1.5 cm in AP dimension. A few posterior fibers of the tendon appear to insert on the greater tuberosity. There is mild fatty atrophy of the supraspinatus muscle. There is also high-grade partial tearing of the anterior fibers of the infraspinatus tendon involving both the articular and bursal surfaces with mild retraction of the bursal surface fibers. There is mild to moderate fatty atrophy of the infraspinatus muscle. There may be mild tendinosis of the subscapularis tendon, but we see no tear and the muscle appears normal. The teres minor muscle and tendon are normal in appearance.SUPRASPINATUS OUTLET: Moderate osteoarthritis affects the acromioclavicular joint with prominent subchondral cyst formation.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral alignment is normal. There is a small amount of fluid within the glenohumeral joint. Mild increased signal intensity within the superior glenoid labrum is suggestive of degeneration.BICEPS TENDON: Given the limitations of this non-arthrographic examination, the biceps tendon appears normal.ADDITIONAL
1.Full-thickness, near complete tear of the supraspinatus tendon and high-grade partial thickness tearing of the infraspinatus tendon with mild rotator cuff muscle fatty atrophy, as described above.2.Acromioclavicular joint osteoarthritis.3.Subcoracoid bursitis.
