Figure 3: A 4-year-old male child presented with weakness of few days in lower extremities and inability to bear weight. There was mild fever. Plain radiograph was unremarkable; (a) A working diagnosis of osteomyelitis of femur was made clinically. Three phase bone scan revealed diffuse increased tracer localization in the distal shaft of right femur (>) and mid shaft of left femur (<); (d) Perfusion and blood pool images did not favor the diagnosis of osteomyelitis; (b,c) Hematologic work up was suggested suspecting this to be bone cortical infarcts. Subsequent work up revealed acute myeloid leukemia
