Shoulder pain and weakness Examination is limited by motion artifact.ROTATOR CUFF: There is a small full-thickness tear of the distal fibers of the supraspinatus tendon which measures approximately 7 mm in the greatest AP dimension. There is additional increased signal intensity of the more proximal fibers of the tendon at the level of the glenoid which suggests some interstitial tearing. There is mild tendinopathy of the more proximal fibers but no significant retraction. The infraspinatus and teres minor tendons are intact. There is mild increased signal intensity of the insertional fibers of the subscapularis suggesting tendinosis.There is minimal fatty atrophy along the myotendinous junctions of the supra and infraspinatus muscles but otherwise the rotator cuff musculature is relatively preserved. There is a lobulated mass just superior to the supraspinatus muscle and adjacent to the acromioclavicular articulation which demonstrates fat signal intensity on all sequences and likely represents a lipoma.SUPRASPINATUS OUTLET: Moderate to severe osteoarthritis affects the acromioclavicular joint. There is no significant subacromial subdeltoid fluid.GLENOHUMERAL JOINT AND GLENOID LABRUM: Mild osteoarthritis affects the glenohumeral joint but alignment is normal. There is degenerative tearing of the anterior and inferior labrum. There is no significant joint fluid.BICEPS TENDON: There is a trace amount of fluid within the biceps tendon sheath of the biceps tendon grossly itself intact.ADDITIONAL
1. Small full-thickness tear of the distal supraspinatus tendon with additional rotator cuff tendinopathy described above.2. Moderate to severe osteoarthritis of the acromioclavicular joint.
