History of head and neck cancer now with shoulder pain and decreased range of motion. Evaluation of the tendons and capsular structures is somewhat limited due to large field-of-view used to image the entire scapula.We see no foci of abnormal signal in the bone marrow to indicate metastases. A small focus of low signal intensity in the humeral head likely represents a benign bone island. Additional patchy intermediate signal intensity in the bones of the shoulder is compatible with residual red marrow. Mild osteoarthritis affects the acromioclavicular joint with small cysts in the distal clavicle.We see no gross rotator cuff tears. No frank fluid is present within the subacromial/subdeltoid bursa. Glenohumeral alignment is within normal limits. There is a small amount of fluid within the glenohumeral joint without large effusion. No gross labral abnormalities are identified. The tendon of the long head of the biceps is within normal limits.We see no abnormal enhancement on postcontrast images.
Mild acromioclavicular joint osteoarthritis in otherwise normal-appearing shoulder without specific findings to account for patient's pain.
