80 year-old male status post excision of right shoulder chondrosarcoma There is no evidence of soft tissue mass or abnormal enhancement to indicate tumor recurrence about the shoulder. Patchy T2 bright foci of signal in the proximal humerus likely represent areas of bone infarction.New full thickness tear of the distal supraspinatus tendon at its insertion with extension of fluid into the subacromial subdeltoid bursa. No significant tendon retraction or muscular atrophy. There is also tendinosis and partial thickness tearing of the distal infraspinatus tendon. The rotator cuff is otherwise intact. The biceps tendon is normally situated within the bicipital groove. The suprascapular notch and spinoglenoid notch appear normal. There is moderate acromioclavicular joint osteoarthritis as well as fluid in the AC joint. Glenohumeral alignment is within normal limits.
