35-year-old male with continued pain in shoulder after subacromial injection and physical therapy. ROTATOR CUFF: The supraspinatus, infraspinatus, and teres minor muscles and tendons appear normal. There is a small, 4-mm focus of increased signal intensity at the insertion of the subscapularis tendon on the lesser tuberosity, compatible with tendinosis or perhaps a tiny insertional tear. Additional linear increased signal intensity along the subscapularis myotendinous junction is compatible with additional mild tendinosis or mild interstitial tearing. The subscapularis muscle otherwise appears normal.SUPRASPINATUS OUTLET: There is mild capsular hypertrophy along the undersurface of the acromioclavicular joint, as well as a small spur along the distal aspect of the clavicle. However no fluid in the subacromial or subdeltoid bursae is present.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is normal. No joint effusion is present. There is a small paralabral cyst along the anterior-inferior labrum that we suspect arises from a small nondisplaced tear of the underlying labrum. The significance of this finding is uncertain. The remainder of the labrum is normal within the limitations of a non-arthrogram study. BICEPS TENDON: Tendon of the long head of the biceps appears normal.
1.Tendinosis and/or small tears involving the subscapularis tendon. Remainder of the rotator cuff appears normal.2.Probable small nondisplaced anteroinferior labral tear associated with a small parameniscal cyst.3.Other findings as above.
