73-year-old female with stage IV lung cancer, bilateral arm pain and numbness with upper back pain. ROTATOR CUFF: There is mild thickening and increased signal intensity of the distal supraspinatus tendon indicating mild tendinosis with a small linear focus of increased signal intensity in the distal fibers which may represent a small interstitial tear. There is perhaps mild bursal surface fraying as well but we see no full thickness tear. Small degenerative cysts are seen in the underlying humeral head. The infraspinatus, teres minor, and subscapularis muscles and tendons appear normal.SUPRASPINATUS OUTLET: Mild osteoarthritis affects the acromioclavicular joint. There is minimal enhancement of the subdeltoid bursa which is probably of no clinical significance.GLENOHUMERAL JOINT AND GLENOID LABRUM: Glenohumeral alignment is within normal limits. There is minimal enhancement of the synovium of the glenohumeral joint which is not necessarily of any clinical significance. There is increased signal intensity of the superior labrum which may represent mild degenerative fraying/tearing but overall the labrum appears normal for age.BICEPS TENDON: Given the limitations of a non-arthrographic study the biceps appears normal. ADDITIONAL
Mild supraspinatus tendinosis and additional degenerative arthritic changes as described above. No findings to suggest metastatic disease to the shoulder.
