46-year-old female with pain and extremely limited range of motion. Evaluate for severe arthrofibrosis. ROTATOR CUFF: There is moderate tendinosis of the supraspinatus tendon with intermediate signal intensity along the undersurface fibers suggesting fraying. There is a 3-4 mm focus of high signal intensity along the undersurface fibers of the supraspinatus seen on image 9 of series 9 which may represent a small articular surface tear. The aforementioned tendinosis extends to involve the anterior fibers of the infraspinatus. There is also focal fluid signal intensity separating the infraspinatus at its insertion on the greater tuberosity indicating a tear. The tear involves the majority of the thickness of the tendon likely disrupting the bursal surface fibers, but probably sparing the articular surface fibers, measuring approximately 4 mm in AP dimension. There is minimal retraction. There is a small focus of signal intensity along the proximal fibers of the infraspinatus along the myotendinous junction which may represent additional tearing. There is mild fatty infiltration along the myotendinous junction of the supraspinatus and infraspinatus. The subscapularis and teres minor muscles and tendons appear intact.SUPRASPINATUS OUTLET: Moderate to severe osteoarthritis affects the acromioclavicular joint with inferior osteophytes. There is a small amount of fluid within the subacromial-subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is increased intermediate signal intensity within the superior labrum compatible with degeneration, but we see no fluid-filled tear within the limitations of a non arthrogram study. The glenohumeral joint alignment is within normal limits. Small glenohumeral joint osteophytes indicate mild osteoarthritis.BICEPS TENDON: The extra-articular portion of the long head of the biceps tendon appears intact. There is intermediate signal intensity within the intra-articular portion of the long head of the biceps suggesting mild tendinosis. ADDITIONAL
1. Tendinosis and partial thickness rotator cuff tearing.2. Moderate to severe osteoarthritis of the acromioclavicular joint with a small amount of fluid within the subacromial-subdeltoid bursa.3. Mild osteoarthritis of the glenohumeral joint. No specific features of adhesive capsulitis.4. Other findings as described above.
