Female 53 years old Reason: evaluate for rotator cuff injury History: R shoulder pain status post fall on right side. ROTATOR CUFF: Thickening and increased signal intensity in the supraspinatus tendon indicating moderate tendinosis. Intermediate signal intensity along the undersurface fibers may represent associated undersurface fraying. There are also more discrete subcentimeter linear foci of fluid signal intensity within the distal fibers of the tendon at its insertion, likely representing small interstitial and undersurface tears. There is a small cyst in the underlying greater tuberosity. There is also a cyst along the musculotendinous junction of the supraspinatus more proximally measuring approximately 2.0 cm in long axis. The supraspinatus muscle appears normal. The tendinosis and undersurface fraying extends posteriorly to involve the infraspinatus tendon but the infraspinatus muscle appears normal. The teres minor muscle and tendon appear normal. The subscapularis muscle and tendon appear normal.SUPRASPINATUS OUTLET: Mild osteoarthritis affects the acromioclavicular joint. The shoulder ligaments are intact.GLENOHUMERAL JOINT AND GLENOID LABRUM: Glenohumeral joint alignment is normal. There is mild osteoarthritis of the glenohumeral joint. There is blunting and signal abnormality in the superior labrum likely reflecting degenerative tearing which extends into the anterior labrum. There is no joint effusion.BICEPS TENDON: The tendon of the long head of the biceps is intact. ADDITIONAL
1. Rotator cuff tendinosis and partial thickness tears as described above.2. Degenerative arthritic changes of the glenohumeral and acromioclavicular joints.3. Note is made of several prominent axillary lymph nodes.4. Multiple tiny foci of signal within the proximal humeral metadiaphysis are nonspecific and while they may simply represent small residual islands of red marrow we cannot exclude an underlying proliferative disorder.
