Left shoulder pain and weakness Note that the examination is limited by motion artifact. Additionally, the patient is internally rotated which limits evaluation of the intra-articular biceps tendon.ROTATOR CUFF: The supraspinatus tendon is diffusely enlarged with increased signal reflecting tendinopathy. There is a small focus of fluid signal within the bursal surface fibers of the supraspinatus indicating a high-grade partial-thickness tear. The infraspinatus tendon appears intact as do the subscapularis and teres minor tendons. There is minimal atrophy of the rotator cuff musculature particularly of the supraspinatus and teres minor.SUPRASPINATUS OUTLET: There is moderate arthrosis of the acromioclavicular joint. A trace amount of subacromial subdeltoid fluid is present.GLENOHUMERAL JOINT AND GLENOID LABRUM: Alignment of the glenohumeral joint is normal. There is severe joint space narrowing and osteophyte formation of the glenohumeral joint indicating moderate to severe osteoarthritis. There is no sizable joint effusion however there is a collection of fluid within the subcoracoid bursa indicating some bursitis.BICEPS TENDON: Evaluation of the biceps tendon is limited by motion and and internal rotation of the humerus. Within these limits, there is increased signal and thickening within a portion of the intra-articular biceps indicating tendinosis. The extra-articular biceps is intact.ADDITIONAL
1. High-grade partial-thickness bursal surface tear of the supraspinatus tendon.2. Subcoracoid bursitis.3. Moderate to severe osteoarthritis of the glenohumeral joint.
