Summary We examined potential clinical and pathologic correlates of seizures among the 3,291 children in the Childhood Brain Tumor Consortium database. Fourteen percent had seizures prior to their hospitalization for a brain tumor. Among children who had a supratentorial tumor, seizures occurred in 22% of those less than 14 years of age. The prevalence of seizures increased to 68% of older teenagers. Among children with an infratentorial tumor, the prevalence of seizures was relatively constant at 6% over all age groups. The onset of seizures began more than one year prior to surgical tumor removal in over half of the children aged five or more with supratentorial tumors, significantly longer than for those of the same age with infratentorial tumors. Almost all children (98.9%) with an infratentorial tumor and seizures had at least one other symptom and more than three-fourths of them had at least three. Eighty-nine percent of children with a supratentorial tumor and seizures had at least one other symptom and more than one-half had at least three symptoms. Regardless of whether the tumor was above or below the tentorium, confusion or stupor and coma were more common in children with seizures than in children without seizures. Among children with supratentorial tumors, symptoms of a declining academic performance or an abnormality of personality, speech, walking, or sensation were significantly more frequent in children with seizures, while visual symptoms (other than visual loss or diplopia) and nausea or vomiting were less frequent. Among children with supratentorial tumors, those who had seizures were more likely to have paralysis of an arm, hand, or face, confusion or stupor, or coma and less likely to exhibit irritability, papilledema, optic atrophy, decreased visual acuity, pupillary abnormalities, or abducens paresis. Among children with infratentorial tumors, those with seizures were significantly less likely to have truncal ataxia, but more likely to experience confusion.
