74-year-old male with left shoulder pain especially with abduction. ROTATOR CUFF: There is a near complete to complete full-thickness tear of the supraspinatus tendon just proximal to its insertion on the greater tuberosity with proximal retraction resulting in a gap of approximately 12 mm. The tear also involves the anterior fibers of the infraspinatus and measures just over 2 cm in the AP dimension. There is thickening and increased signal intensity of the retracted supraspinatus tendon likely representing moderate tendinosis. There is mild edema along the superficial margin of the supraspinatus muscle which may reflect a strain. The infraspinatus muscle appears intact. The subscapularis and teres minor muscles and tendons appear intact.SUPRASPINATUS OUTLET: Mild osteoarthritis affects the acromioclavicular joint. There is fluid within the subacromial/subdeltoid bursa extending into the subcoracoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is a small to moderate sized glenohumeral joint effusion. There is fluid interposed between the superior labrum and the underlying glenoid likely representing a tear.BICEPS TENDON: The tendon of the long head of the biceps appears intact.
Near-complete to complete full-thickness tear of the supraspinatus tendon with involvement of the anterior fibers of the infraspinatus tendon and other findings as described above.
