Evaluate for early signs of avascular necrosis. Severe osteoarthritis affects the right hip with severe cartilage loss and bone-on-bone apposition anteriorly and superiorly. There is edema-type signal within the acetabular dome that we suspect is degenerative in etiology. We see no specific imaging features of avascular necrosis. Small right hip joint effusion containing intermediate signal intensity likely representing synovitis and debris. There is degeneration and tearing of the anterior labrum.On the large field-of-view images, moderate osteoarthritis affects the right hip.The musculature appears intact. There is metallic susceptibility artifact from tubal ligation clips.
Severe osteoarthritis of the right hip and other findings as described above without evidence of avascular necrosis.
