Patient with persistent pain in right shoulder, status post dog attack 3 months ago. Dog pulled on distal arm and shook patient. No direct attack at the shoulder joint. ROTATOR CUFF: Supraspinatus, infraspinatus, and teres minor tendons appear normal. The muscles likewise appear normal. There is a 3 to 4 mm tiny focus of signal intensity within the superior fibers of the subscapularis tendon, which may represent a small interstitial tear but this is of questionable clinical significance. The subscapularis muscle otherwise appears normal.SUPRASPINATUS OUTLET: Mild osteoarthritis affects the acromioclavicular joint. We see no fluid in the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: Glenohumeral joint alignment is normal. We see no joint effusion. Given the limitations of a nonarthrogram study, the glenoid labrum and articular cartilage appear normal. Small cysts within the anteromedial and posterolateral humeral head may be degenerative in etiology.BICEPS TENDON: Given the limitations of nonarthrogram study, the tendon of the long head of the biceps appear normal. There is small amount of fluid in the tendon sheath which is not necessarily of any clinical significance.
1.Tiny focus of signal intensity in the superior fibers of the subscapularis tendon may represent small interstitial tear, but this is of questionable clinical significance and the remainder of the rotator cuff is unremarkable.2.Mild osteoarthritis of the acromioclavicular joint and other findings as described above.
