The variety and distribution of skeletal lesions in children with acut
e lymphoblastic leukemia is rarely seen in other diseases. Skeletal ra
diographic changes that can occur in a child with acute leukemia inclu
de diffuse osteopenia, metaphyseal bands, periosteal new bone formatio
n, geographic osteolysis, osteosclerosis, mixed osteolysis and scleros
is, and permeative destruction. It is important for orthopedic surgeon
s to recognize the skeletal manifestations of acute leukemia of childh
ood because the physician who initially evaluates the child will often
be an orthopedic surgeon, and a delay in diagnosis has an adverse aff
ect on survival.
