63-year-old female with severe left shoulder pain with limited range of motion. Evaluate for rotator cuff tear. Motion artifact slightly limits evaluation.ROTATOR CUFF: There is discontinuity of the fibers of the subscapularis tendon near its insertion with associated high signal intensity on proton density and T2-weighted images consistent with a full-thickness tear. The subscapularis muscle appears normal. There is thickening of the supraspinatus tendon with associated intermediate signal intensity indicating tendinosis. The supraspinatus muscle appears normal. The infraspinatus tendon appears normal. There is mild fatty infiltration of the infraspinatus muscle. The teres minor tendon and muscle appear normal.SUPRASPINATUS OUTLET: No significant abnormality noted.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint is in anatomic alignment. There is a small amount of fluid in the glenohumeral joint without frank effusion. The glenoid labrum appears grossly normal on this nonarthrogram study.BICEPS TENDON: Small amount of fluid within the tendon sheath of the long head of the biceps tendon communicating with the glenohumeral joint fluid. The tendon of the long head of the biceps appears normal.ADDITIONAL
1. Full-thickness tear of the subscapularis tendon.2. Tendinosis of the supraspinatus tendon.3. Thickening of the coracohumeral ligament raising the possibility of adhesive capsulitis ('frozen shoulder').
