43-year-old female with left shoulder pain. ROTATOR CUFF: The supraspinatus muscle and tendon are normal. There is mild fatty atrophy along the myotendinous junction of the infraspinatus, but otherwise the muscle and tendon appear normal. The subscapularis and teres minor muscles and tendons appear intact.SUPRASPINATUS OUTLET: There is a trace amount of fluid within the subacromial/subdeltoid bursa, not necessarily of any clinical significance. The acromioclavicular joint is within normal limits.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is within normal limits. There is a small amount of fluid within the glenohumeral joint, but no frank effusion. Although we see no fluid-filled labral tear, there is increased intermediate signal intensity within the anterior inferior labrum, extending into the anterior superior labrum, that may reflect degeneration or the sequela of prior tearing. The posterior superior labrum appears slightly attenuated, but this may represent normal anatomic variation for this patient.BICEPS TENDON: There is a small amount of fluid within the biceps tendon sheath which may represent a mild tenosynovitis.

1. Normal-appearing rotator cuff.2. Increased signal intensity within the anterior labrum may represent degeneration or the sequela of prior tearing. If there are clinical signs and symptoms of instability, this could be further evaluated with MR arthrography.3. Small amount of fluid within the biceps tendon sheath may represent a mild tenosynovitis, but this is equivocal.
