Epilepsy and low grade gliomas in pediatric neurosurgery.

A series of 33 children affected by low grade gliomas and epilepsy is reported. Seizures are often the only symptom of these patients; intracranial hypertension and focal neurological signs may be present too. All children were operated on; tumor removal was performed in 21 cases, tumor removal associated with corticectomy and/or lobectomy was performed in 12 patients. The treatment of epilepsy has been more effective in the first group of patients with only lesionectomy than in the second one, in which neoplasm removal was coupled with nervous system tissue asportation.
