52-year-old female with pain and weakness ROTATOR CUFF: Metallic susceptibility artifact within the posterior humeral head and adjacent soft tissues likely reflects prior rotator cuff repair. We see no full thickness rotator cuff tear. The supraspinatus tendon can be traced to its insertion on the greater tuberosity. The tendon is thinned, in part due to undersurface tearing with delamination and retraction of undersurface fibers to the level of the top of the humeral head. The undersurface tear measures approximately 1 cm in AP dimension. There is also tearing along the bursal surface fibers of the supraspinous tendon. Overall, the tearing involves greater than 50% of the tendon thickness. More proximally the tendon appears thickened and of slightly heterogeneous signal, compatible with tendinosis. There appears to be mild fatty atrophy of the supraspinatus muscle along the myotendinous junction, but the muscle appears otherwise normal. There may be mild tendinosis of the infraspinatus tendon, which otherwise is within normal limits. The teres minor tendon appears intact, although increased signal intensity within the muscle could reflect mild subacute denervation atrophy, appearing similar to the prior exam. The subscapularis muscle and tendon appear normal.SUPRASPINATUS OUTLET: There is mild osteoarthritis affecting the acromioclavicular joint. There is perhaps trace fluid in the subacromial-subdeltoid bursa, but no frank bursitis.GLENOHUMERAL JOINT AND GLENOID LABRUM: No joint effusion. The superior labrum appears slightly blunted, which may reflect chronic fraying or degenerative tearing. There is no fluid-filled labral tear.BICEPS TENDON: The biceps tendon appears thin, but intact.
1. Postoperative changes of rotator cuff repair with thinning of the supraspinatus tendon, likely due to articular and bursal surface tearing, as well as additional findings as described above. No full-thickness rotator cuff tear is identified.
