Cortical irregularity of both femoral heads. Altered marrow texture with geographic areas of hypointensity on T1WI and hyperintensity at T2WI, more affecting the right femoral head with extension to the neck and visualized proximal femoral shaft marrow (bilateral avascular necrosis).
Mild bilateral hip joint effusion.
Altered marrow texture with heterogeneous appearance of the bone marrow of the pelvic bones with multiple marrow lesions extending to the bone cortex is suggestive of osteonecrosis.
