Male, 70 years old. Shoulder pain Several sequences are limited by patient motion artifact.ROTATOR CUFF: There is a small linear focus of increased signal intensity within the insertional fibers of the rotator cuff at the junction of the supraspinatus and infraspinatus tendons, indicating a concealed insertional tear. The tear involves approximately 50% of the tendon thickness and measures just under 1 cm in AP diameter. Mild tendinosis is noted within the supraspinous and infraspinatus tendons more proximally. The supraspinatus and infraspinatus muscles appear normal. The teres minor tendon and muscle appear normal. There is perhaps mild tendinosis of the subscapularis which otherwise appears intact. There is a small lipoma within the subscapularis muscle, unchanged from the prior study. The subscapularis muscle otherwise appears normal.SUPRASPINATUS OUTLET: Moderate osteoarthritis affects the acromioclavicular joint. There is trace fluid in the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: Mild osteoarthritis affects the glenohumeral joint. Evaluation of the labrum is limited due to lack of intra-articular contrast and motion artifact, but deformity and increased signal within the superior labrum likely represents degenerative tearing appearing similar to that seen on the prior study. There is a small amount of fluid within the glenohumeral joint, but there is no large effusion.BICEPS TENDON: Given the limitations of a nonarthrogram study, the tendon of the long head of the biceps appears normal.
Osteoarthritis of the left shoulder with a new concealed insertional tear of the supraspinatus and infraspinatus tendons as described above.
