title: Cerebral tumors in children presenting with epilepsy.
abstract: The records of 20 children with seizures who had cerebral tumor confirmed histologically between 1979 and 1989 have been reviewed. These patients represented 2.9% of all children presenting with seizures. Forty percent were aged 15 months or younger, all of whom presented with partial seizures. Initial misdiagnosis of seizures occurred in 25% of these infants. Examination was normal in 75% of the study group. Behavior disturbance was present in 50%, with deterioration occurring in 60% of these. Electroencephalograms revealed focal abnormalities in 62% and generalized abnormalities in 25% when performed. Cranial ultrasound was performed in two cases, with false-negative results. Computed tomographic scan findings were not diagnostic of tumor in 40%. Magnetic resonance imaging confirmed the presence of tumor in all children in whom it was performed. Tumors most frequently involved the temporal lobes (55%) and the frontal lobes (40%). Surgical intervention resulted in considerable improvement in seizure control in 75%. Surgery is useful in the control of tumor-related seizures and should be considered early in the treatment of this disorder. Suspicion of tumor should increase when seizures are partial or refractory, particularly if intelligence and physical examination are normal or if there is progressive deterioration in behavior. The most appropriate type of brain imaging is magnetic resonance imaging scan.
