73-year-old male with left shoulder pain, evaluate for tendon injury ROTATOR CUFF: There is a fluid signal intensity within the distal supraspinatus tendon at its insertion on the greater tuberosity. This tear disrupts the bursal surface fibers, but appears to spare the articular surface fibers. There is 5 mm retraction of the bursal surface fibers. Overall, the tear involves at least 50% of the tendon thickness and is approximately 1.5 cm in the AP dimension. It appears to propagate posteriorly as an interstitial tear of the anterior insertional fibers of the infraspinatus tendon. The majority of the infraspinatus tendon, however, appears intact. There is minimal fatty infiltration along the myotendinous junction of the supraspinatus and infraspinatus, but otherwise the muscles appear normal. The teres minor tendon and muscle appears normal. The subscapularis tendon and muscles are within normal limits.SUPRASPINATUS OUTLET: Mild osteoarthritis affects the acromioclavicular joint. There is perhaps a small 7 mm ossicle along the anterior aspect of the acromion process. There is a small amount of fluid in the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is within normal limits. There is a small amount of fluid in the glenohumeral joint, but no effusion. The superior labrum is attenuated, likely representing chronic degenerative tearing. Inferiorly, the labrum is within normal limits for age. Mild osteoarthritis affects the glenohumeral joint.BICEPS TENDON: The biceps tendon and long head of the biceps appears normal. ADDITIONAL
Insertional bursal surface tear of the supraspinatus tendon, and other findings as described above.
