Symptomatic epilepsy associated with intracranial calcifications in children with acute lymphoblastic leukemia (ALL).

Acute and long-term sequels of central nervous system (CNS) prophylaxis with irradiation and intrathecal chemotherapy in children suffering from acute lymphoblastic leukemia (ALL) include vasculopathies, leucoencephalopathies, intracranial calcifications, intellectual and neurological impairment. We report two children at the age 5 and 8 years who manifested partial motor or complex seizures and intracranial calcifications 2-4 years after the diagnosis of ALL had been established. The occurrence of these disorders was much earlier than reported in the literature. Both children received prophylactic CNS treatment with irradiation and intrathecal methotrexate (MTX). Their brain CT scans and EEG had been normal before the first epileptic seizure was registered. Children are now seizure free on carbamazepine, and a boy with complex partial and myoclonic seizures is also on valproate and vigabatrine. Symptomatic epilepsy associated with intracranial calcifications and persisting EEG changes might occur as side effects of ALL treatment.
