Left shoulder pain and weakness ROTATOR CUFF: There is a full-thickness tear of the supraspinatus tendon which is complete with retraction to the level of the glenoid. This tear extends to involve most if not all of the infraspinatus tendon which is also retracted. There is mild to moderate atrophy of the supraspinatus musculature with severe atrophy of the infraspinatus musculature. The teres minor tendon and muscle are normal. There is thickening and increased signal of the subscapularis reflecting tendinosis. Superimposed upon this tendinosis is full-thickness tearing of the insertional superior fibers of the subscapularis. There is mild associated atrophy of the subscapularis muscle.SUPRASPINATUS OUTLET: There is moderate acromioclavicular arthrosis.GLENOHUMERAL JOINT AND GLENOID LABRUM: The humeral head is high riding which abuts the undersurface of the acromium. There is moderate glenohumeral osteoarthritis with cartilage loss and subchondral cystic changes noted. Degenerative changes of the anterior and superior labrum are noted. A small amount of fluid is present within the subdeltoid bursa. There is fat signal within the subscapularis recess which may reflect an area of focal lipomatous arborescens.BICEPS TENDON: Biceps tendon is not clearly seen within the superior portion of the bicipital groove which is likely the result of tearing. The tendon is seen further distally however a surface defect is present reflecting a partial tear.ADDITIONAL
Large rotator cuff tear which includes complete full-thickness tears of the supra and infraspinatus tendons and partial tearing of the subscapularis tendon. Additional findings of the shoulder are described above.
