44-year-old female with history of right hip pain. Evaluate for avascular necrosis. ARTICULAR CARTILAGE AND BONE: Moderate osteoarthritis affects the right hip with articular cartilage thinning particularly along the anterior/superior aspect of the joint with cyst formation in the underlying acetabulum along with osteophyte formation. We see no specific features of avascular necrosis.There is slight prominence of the anterolateral aspect of the femoral head/neck junction with an alpha angle of approximately 60 degrees compatible with mild CAM deformity.Osteoarthritis affects the left hip to a slightly lesser degree.ACETABULAR LABRUM: There is branching signal abnormality within the anterior labrum likely representing extensive degenerative tearing that extends into the superior labrum as well. The posterior labrum appears relatively intact.SOFT TISSUES: The ligamentum teres is intact. The visualized musculature appears normal.ADDITIONAL
