Assess right hip avascular necrosis There is serpentine signal abnormality within the epiphysis of the right femoral head indicating avascular necrosis involving the majority of the subchondral bone. The necrotic bone is of predominantly fat signal intensity on T1-weighted images. A thin curvilinear band of subchondral intermediate signal intensity likely represents a subchondral fracture, but I see no frank articular surface collapse. There is edema of the femoral head extending into the neck and intertrochanteric region. There is a small amount of fluid in the joint, but no large effusion.Similar although slightly less extensive avascular necrosis affects the left femoral epiphysis, with edema of the left femoral head extending into the left femoral neck. There is small amount of fluid in the joint, but no large effusion. The remainder of the bone marrow signal intensity is normal. The sacroiliac joints appear normal. The musculature appears normal. This study was not protocoled for detailed evaluation of the pelvic viscera, but I see no gross abnormalities. There are nodular subcutaneous lesions in the mons pubis which may represent cysts.
Avascular necrosis of the femoral heads and other findings as above.
