Male, 44 years old. Left shoulder pain ROTATOR CUFF: The supraspinatus tendon and muscle appear intact. The infraspinatus tendon and muscle appear intact. The teres minor tendon and muscle appear intact. The subscapularis tendon appears slightly thickened, which may reflect tendinosis, but we see no tear.SUPRASPINATUS OUTLET: Moderate osteoarthritis affects the acromioclavicular joint with osteophytes resulting in slight impression on the superior fibers of the supraspinatus.GLENOHUMERAL JOINT AND GLENOID LABRUM: Moderate osteoarthritis affects the glenohumeral joint with near full-thickness to full-thickness cartilage loss along the glenoid posteriorly associated with subchondral cysts. There is extensive tearing of the labrum involving the superior, anterior, and posterior labrum in a near-circumferential manner. Bandlike low signal intensity extending from the inferior margin of the glenoid into the axillary recess likely represents a displaced cartilage flap with additional poorly defined intermediate signal intensity in the axillary recess likely representing a combination of debris and synovitis.BICEPS TENDON: There is mild thickening and increased signal intensity of the tendon of the long head of biceps at its transition from the rotator interval to the intertubercular groove, suggesting mild tendinosis. There is a 1.3 cm lobulated focus of intermediate signal intensity within the biceps tendon sheath that presumably represents a displaced cartilage fragment.
Osteoarthritis of the glenohumeral joint with extensive tearing of the labrum and displacement of cartilaginous fragments as described above.
