55-year-old male with history of left shoulder pain. ROTATOR CUFF: Complete, full thickness tear of the supraspinatus tendon, with delamination of the tendon and retraction of the deep fibers to approximately the level of the glenohumeral joint. Increased signal intensity in the retracted tendon likely represents tendinosis. The tear extends posteriorly to involve the anterior half of the infraspinatus tendon. Increased signal intensity in the intact portion of the infraspinatus tendon is compatible with tendinosis. There is mild fatty atrophy of the myotendinous junction of the infraspinatus, otherwise the supraspinatus and infraspinatus muscles appear normal. The subscapularis and teres minor tendons and muscles are within normal limits.SUPRASPINATUS OUTLET: Moderate to severe osteoarthritis affects the acromioclavicular joint. There is a small amount of fluid in the subacromial/subdeltoid bursa, as well as foci of intermediate signal intensity which likely represent synovitis and debris. There is narrowing of the acromiohumeral interval to 5 mm, consistent with a chronic rotator cuff tear.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral articular cartilage appears normal for age. A small amount of fluid undercuts the superior labrum on multiple slices, which we suspect represents a SLAP tear extending into the superior aspect of the anterior labrum, although, this could conceivably represent an unusually long sublabral recess. A small glenohumeral joint effusion is present, with a small amount of synovitis superiorly within the joint.BICEPS TENDON: The tendon of the long head of the biceps is within normal limits.
Full-thickness rotator cuff tear and other findings as described above.
