Male, 34 years old. Reason: Rotator cuff tear? History: Pain > 90 ROTATOR CUFF: There is mild edema within the superficial aspects of the supraspinatus and infraspinatus muscles, more prominently near the myotendinous junction. There is minimal tendinopathy of the infraspinatus tendon, but no discrete tear is identified. The supraspinatus tendon is intact. The subscapularis and teres minor muscles and tendons are intact.SUPRASPINATUS OUTLET: There is marked bone marrow edema involving the clavicular head and the acromion process, with associated thickening and increased signal of the superior aspect of the acromioclavicular ligament.GLENOHUMERAL JOINT AND GLENOID LABRUM: The ABER view is nondiagnostic. The articular cartilage and glenoid labrum are grossly intact, within the limits of nonarthrogram study.BICEPS TENDON: The tendon of the long head of the biceps is normal. ADDITIONAL
1.Marked bone marrow edema at the acromioclavicular joint is nonspecific but may be due to repeated trauma or inflammatory process. If symptoms are unilateral, this increases concern for a more acute process such as infection.2.Mild edema involving the superficial aspects of the supraspinatus and infraspinatus muscles of uncertain etiology, but may be secondary to adjacent inflammatory changes from the acromioclavicular joint.
