Myelopathy. Shoulder pain. ROTATOR CUFF: There is a near full-thickness bursal surface tear of the supraspinatus involving greater than 50% of the tendon with at the level of its insertion on the greater tuberosity measuring approximately 12 mm in AP dimension. There is no significant retraction. There is thickening and intermediate signal intensity within the supraspinatus indicating moderate tendinosis. There is extension of this tearing to involve the anterior fibers of the infraspinatus. There is marked fatty atrophy of the infraspinatus muscle. There is interstitial tearing of the subscapularis at the level of its insertion. The teres minor muscle and tendon appear intact.SUPRASPINATUS OUTLET: There is no significant fluid within the subacromial subdeltoid bursa. Note is made of an os acromiale. Mild osteoarthritis affects the acromioclavicular joint.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is anatomic. There is thickening and intermediate signal intensity within the posterior superior labrum likely representing a combination of degeneration and degenerative tearing. There is also heterogeneity of the anterior labrum which also likely represents a combination of degeneration and degenerative tearing.BICEPS TENDON: The tendon of the long head of the biceps appears intact. The tendon appears perched upon the lesser tuberosity at its transition into the rotator interval suggesting minimal subluxation. There is fluid within the tendon sheath which may represent fluid extension from the joint versus a mild tenosynovitis. ADDITIONAL
1. High-grade insertional tear of the bursal surface fibers of the supraspinatus without significant retraction. There is extension of this tear to involve the anterior fibers of the infraspinatus. Interstitial tearing of the subscapularis.2. The tendon of the long head of the biceps appears perched upon the lesser tuberosity suggesting minimal subluxation.3. Osteoarthritis of the shoulder. Other findings as described.
