54-year-old female patient with right shoulder pain and concern for supraspinatus tendon tear. ROTATOR CUFF: There is mild increased signal intensity in the supraspinatus tendon, indicating mild tendinosis, but we see no fluid-filled tear and the muscle is intact. There is mild increased signal intensity in the anterior fibers of the infraspinatus tendon suggesting tendinosis, but we see no fluid-filled tear and the muscle is intact. The subscapularis and teres minor tendons and muscles are within normal limits.SUPRASPINATUS OUTLET: There is an os acromiale with a small subchondral cyst, likely degenerative. There is also a lobulated lesion with near fluid signal in the distal clavicle that measures 18 mm in greatest dimension with a small component also noted dorsal to the clavicle, which may represent a degenerative cyst or an intraosseous ganglion. There is minimal impression upon the superior muscle fibers of the supraspinatus by the distal clavicle. There is no free fluid in the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is no joint effusion. Glenohumeral alignment is within normal limits. There is blunting and mild abnormal increased signal intensity in the anterior labrum, which may represent degenerative changes and perhaps mild degenerative tearing, but we see no fluid-filled tear. Given the limitations of this non-arthrographic study, the remaining labrum appears normal.BICEPS TENDON: The tendon of the long head of the biceps is within normal limits.
1.Mild rotator cuff tendinosis without fluid-filled tear.2.Os acromiale with osteoarthritic changes as described above and additional cystic lesion in the distal clavicle, which is likely degenerative in etiology or perhaps represents an intraosseous ganglion.3.Blunting and heterogeneity of the anterior glenoid labrum likely represents degenerative changes.
