Prognosis and treatment of seizures in children with acute lymphoblastic leukemia.

We reviewed the records of 127 consecutive pediatric patients with acute lymphoblastic leukemia (ALL) to determine the incidence, timing, etiologies, and recurrence rate of seizures in this population. Patients with ALL and seizures were identified retrospectively by review of the records of all pediatric ALL patients who were diagnosed and treated during the years 1983 through March 1993 in a large tertiary-care hospital. Seventeen patients (13%) developed one or more seizures.
