Reason: Evaluate for shoulder pain etiology History: left shoulder pain ROTATOR CUFF: There is increased signal intensity within the anterior fibers of the distal supraspinatus tendon at its insertion on the greater tuberosity indicating a tear that involves the undersurface fibers, which we suspect extends through the entire thickness of the tendon, measuring approximately 1 cm in the AP dimension. There is no significant retraction. More proximally within the supraspinatus tendon, there is focal intermediate signal intensity that involves the majority of the thickness of the tendon including the articular surface fibers, which we believe spares the bursal surface fibers, likely representing a high-grade partial-thickness tear with less than 1 cm of retraction of the deep fibers of the tendon. The margins of the suspected tear are difficult to discern due to adjacent tendinosis, which also extends posteriorly to involve the anterior fibers of the infraspinatus. There is mild fatty atrophy at the level of the myotendinous junction of the supraspinatus and infraspinatus. The subscapularis and teres minor muscles and tendons appear intact.SUPRASPINATUS OUTLET: There is a small amount of fluid within the subacromial/subdeltoid bursa which supports an anterior full thickness rotator cuff tear. The acromioclavicular joint is normal for age.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is degeneration of the articular cartilage of the glenoid, anteriorly, with underlying subchondral cyst formation indicating mild osteoarthritis. There is linear intermediate signal intensity traversing the mid anterior labrum which likely represents a tear of questionable significance. There is increased signal intensity within the joint that likely represents a combination of a mild synovitis as well as a small amount of fluid within the joint.BICEPS TENDON: The tendon of the long head of the biceps appears intact.
1. Supraspinatus tears and tendinosis as described above.2. Mild osteoarthritis of the glenohumeral joint and other findings as described above.
