Avascular necrosis of the femoral head as a complication of chronic myelogenous leukaemia.
A 17-year-old male patient complaining of intense pain in his right hip was found to be suffering from chronic myelogenous leukaemia. Preliminary X-rays and bone scintigraphy did not suggest avascular necrosis of the femoral head. Magnetic resonance imaging (MRI) did, however, reveal leukaemic infiltration of the femoral neck and generalised ischeamia in the femoral head. Further, MRI carried out 4 months later disclosed typical signs of osteonecrosis, despite previous indications of an improvement under chemotherapy. Flattening of the head of the femur appeared in radiographs taken in the 9th month. In the 12th month, recurrence of pain made it necessary to perform a total hip arthroplasty. Anatomo-pathological investigation confirmed both the necrosis and the leukaemic invasion.
