Reason: right shoulder chondrosarcoma, check for recurrence History: check for recurrence We see no soft tissue mass or enhancement to indicate a recurrence of the patient's soft tissue sarcoma. There is signal abnormality within the medial clavicle and proximal humeral diaphysis which appears similar to the prior study and may represent post radiation therapy changes. Moderate osteoarthritis affects the acromioclavicular joint. Mild osteoarthritis affects the glenohumeral joint with a mild glenohumeral joint synovitis. Although this examination was not protocoled for detailed evaluation of the rotator cuff, there is thinning of the supraspinatus tendon likely reflecting chronic attritional tearing with additional more focal partial thickness undersurface tearing, distally, that is comparable to that seen on the prior examination. There is also a partial-thickness undersurface tear of the distal infraspinatus at the level of its insertion, which appears similar to the prior study. There is perhaps trace fluid and enhancement of the subacromial subdeltoid bursa.
1. No evidence of tumor recurrence. Presumed treatment-related changes of the clavicle and humerus as described above.2. Osteoarthritis of the shoulder, partial-thickness rotator cuff tears, and other findings as described above.
