ACETABULAR LABRUM: Although this examination was not protocoled for evaluation of acetabular labrum, no discrete labral tear is identified.ARTICULAR CARTILAGE AND BONE: Note is made of curvilinear signal abnormality within the right femoral head consistent with avascular necrosis. Additionally, there is diffuse increased signal abnormality within the left femoral head and neck also consistent with avascular necrosis. The possibility of subchondral fracture cannot be excluded and correlation with dedicated left hip radiographs is recommended.SOFT TISSUES: There is generalized muscle atrophy bilaterally. ADDITIONAL
