66-year-old female. Left shoulder pain, concern for a rotator cuff tear. ROTATOR CUFF: There is increased signal intensity within the supraspinatus tendon at the 12 o'clock position indicating tendinosis and perhaps mild associated surface fraying. There are small cysts in the underlying humeral head. We see no discrete rotator cuff tear. The supraspinatus muscle is intact. The infraspinatus, subscapularis, and teres minor tendons and muscles are intact.SUPRASPINATUS OUTLET: Mild osteoarthritis affects the acromioclavicular joint resulting in minimal impression on the superior fibers of the supraspinatus. There is trace fluid in the subdeltoid bursa without frank bursitis.GLENOHUMERAL JOINT AND GLENOID LABRUM: Although we see no fluid signal intensity within the superior labrum, intermediate signal intensity within the labrum may reflect a tear. Apparent enlargement of the anterior superior labrum on the axial images may be due to an adherent middle glenohumeral ligament. Both the anterior and posterior labrum are slightly ill-defined, which may reflect additional tearing. There is increased linear signal intensity within the articular cartilage along the anterior inferior glenoid suggesting delamination. Small glenohumeral joint osteophytes are noted. There is a small amount of fluid in the glenohumeral joint without a frank effusion.BICEPS TENDON: The tendon of the long head of the biceps appears normal given the limitation of this non-arthrogram study.ADDITIONAL
1. Increased signal intensity in the supraspinatus tendon suggests tendinosis but we see no discrete tear.2. Mild osteoarthritis affects the acromioclavicular and glenohumeral joints.3. Findings suggesting degeneration or tearing of the labrum as described above, of questionable clinical significance. This can be further evaluated with MR arthrography if clinically warranted.4. Enlargement and increased signal intensity of the coracoclavicular ligament may reflect mucoid degeneration, perhaps from old trauma.
