58-year-old female with increasing left shoulder pain for several months, worse with movement. History breast cancer, never recurrent. Evaluate for metastases, tears. ROTATOR CUFF: There is mild increased signal intensity within the supraspinatus and infraspinatus tendons, with perhaps mild undersurface fraying but no discrete tear. The supraspinatus and infraspinatus muscles appear normal. A small cyst is seen in the underlying posterior aspect of the humeral head, likely degenerative in etiology. The teres minor and subscapularis muscles and tendons appear normal.SUPRASPINATUS OUTLET: Mild osteoarthritis affects the acromioclavicular joint. No fluid is seen in the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: Mild osteoarthritis affects the glenohumeral joint, with delamination of the articular cartilage along the superior aspect of the humeral head. There is a small glenohumeral joint effusion with extension to the subscapular recess. Blunting and increased signal intensity of the superior labrum likely represents degenerative tearing. The inferior labrum appears normal.BICEPS TENDON: Mild thickening and increased signal intensity of the intra-articular aspect of the long head of the biceps tendon is present, suggesting tendinosis. Fluid surrounding the extra-articular portion of the long bead of the biceps tendon may represent tenosynovitis or simply extension of fluid from the glenohumeral joint. ADDITIONAL
1.No evidence of metastatic disease. 2.Rotator cuff tendinosis and possible mild undersurface fraying without a discrete tear. 3.Osteoarthritis of the glenohumeral joint and other findings as described above.
