Epilepsy and brain tumors in infancy and adolescence.
Four boys and four girls with brain tumors who were admitted to our department in the last 8 years are herein described. They presented with epileptic fits, which began before the age of 14 years, with neither intracranial hypertension nor localizing signs during the first 6 months of the illness. The length of time between the first fit and the diagnosis of a tumor ranged from 2 months to 11 years (median of 3 years), during which period all patients but one received anticonvulsant therapy. The nontreated patient was under psychiatric treatment for 1 year. The electroencephalographic evolution was disconcerting, showing asymmetry of the recording with association of slow polymorphic waves and acute irregular waves, suggesting encephalitis. The neuroradiological diagnosis was made by cerebral arteriography in one patient and in the others by angiography and CT scans (which revealed hypodense cerebral areas in five cases and hyperdense areas in the other two). The histology of the tumor was that of a grade I astrocytoma in six cases; a grade III oligondendroglioma in one case, and a meningioma in the other. All patients underwent surgical treatment. Four also received radiation therapy, two for a partially excised astrocytoma and one each for an oligodendroglioma and a meningioma. Postoperatively, all patients were put on anticonvulsant drug therapy. There were no mortalities. To date, only one astrocytoma has recurred. The sequellae observed were hemiparesis in one case and marked psychomotor deficit in another. These two patients also still have epileptic fits. The others are all psychologically and neurologically normal, and two are now off antiepileptic drugs.
