Left hip pain Moderate to severe osteoarthritis affects the hip with joint space narrowing and cystic changes involving both the femoral head and acetabulum. There is a moderate-sized joint effusion which demonstrates intermediate signal intensity and enhancement suggesting complex fluid and synovitis. Synovial thickening is also evident. There is abnormal morphology and signal intensity of the anterior and superior labrum representing degeneration and tearing. The marrow signal of the proximal femur is otherwise normal. The surrounding soft tissues and muscles of the left hip are normal.
