A 6½-year-old boy had developed acute lymphoblastic leukemia and was treated with
systemic chemotherapy, intrathecal triple drug regimen and prophylactic cranial irradiation.
After 10 years he developed anaplastic astrocytoma of the postero-superior cerebellum
on the left side while leukemia was in remission. He was treated with surgical excision,
followed by adjuvant three dimensional conformal radiotherapy and is on salvage chemotherapy
with temozolamide. It is possible that the anaplastic astrocytoma may be a radiation
induced malignancy.
