39-year-old male with left shoulder pain and weakness. Difficulty reaching. Suboptimal evaluation on multiple sequences due to patient motion artifact.ROTATOR CUFF: There is intermediate signal abnormality within the supraspinatus tendon indicating mild tendinosis. The supraspinatus muscle and tendon appear intact. There is a small partial thickness undersurface tear of the infraspinatus muscle at the level of its insertion on the greater tuberosity measuring approximately 6 mm in the AP dimension without significant retraction, involving less than 50% of the tendon width. There is interstitial tearing of the infraspinatus at the level of the myotendinous junction. The infraspinatus muscle appears intact. The subscapularis and teres minor muscles and tendons appear intact.SUPRASPINATUS OUTLET: There is no significant fluid within the subacromial subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is anatomic. Although this examination was not protocoled for evaluation of the acetabular labrum, there is heterogeneity and increased signal abnormality within the anterior superior glenoid labrum with associated deformity suggesting degenerative tearing.BICEPS TENDON: There is circumferential fluid within the tendon sheath of the long head of the biceps which may represent fluid extension from the joint versus a mild tenosynovitis. The tendon of the long head of the biceps appears intact. ADDITIONAL
1. Findings consistent with avascular necrosis of the humeral head as described above.2. Small partial-thickness rotator cuff tear without evidence of a full-thickness rotator cuff tear or retraction.
