55-year-old female with lateral shoulder pain. Evaluation is limited by artifact of unknown etiology.ROTATOR CUFF: There is a full thickness tear of the supraspinatus tendon at its insertion on the greater tuberosity with just under 1 cm of proximal retraction. The tear is just over 1 cm in the AP dimension. There are subchondral cysts in the underlying humeral head. The supraspinatus muscle appears intact. The infraspinatus tendon appears intact. The infraspinatus muscle appears intact, although there is mild fatty infiltration along the myotendinous junction of the infraspinatus muscle. The teres minor and subscapularis muscles and tendons appear intact. SUPRASPINATUS OUTLET: Mild osteoarthritis affects the acromioclavicular joint. There is a small amount of fluid within the subacromial/subdeltoid bursa likely related to the full-thickness supraspinatus tear. There are foci of intermediate signal intensity within the bursal fluid, likely representing synovitis or debris. GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is within normal limits. There is no joint effusion. There is intermediate signal intensity within the posterior aspect of the superior labrum that may reflect degeneration or degenerative tearing, but we see no fluid-filled labral tear.BICEPS TENDON: The long head of the biceps tendon appears intact. ADDITIONAL
1. Full-thickness mildly retracted tear of the supraspinatus tendon.2. Mild osteoarthritis of the acromioclavicular joint.3. Lipoma and other findings as described above.
