Epilepsy and cerebral tumor

OBJECTIVE: To determine clinical and pathological features with seizures associated brain tumors. PATIENTS AND METHODS: This was a retrospective study through of an Epilepsy Program Protocol where we studied fifty patients admitted at Hospital Universitario Cajuru of Curitiba, Brazil, in 1996-1997. RESULTS: We studied 36 males and 14 females, aged 6 and 81 years old (mean 40.5). Twenty six patients had tonic-clonic seizures, 13 had simple partial secondarily generalized, 8 had simple partial, 2 complex partial and one with simple partial progressing to complex partial seizure. CT showed parietal expansive lesion on 14 cases, frontal expansive lesion on 14 cases, frontoparietal on 5; intraventricular tumor, sella turcica, temporal temporoparietal and fronto-temporo-parietal expansive lesion 2 on each case, and suprasellar lesion, centrum semiovale, cerebello-pontine angle, ventricular trigone, fronto-naso-etmoidal and brain stem 1 on each case. All patients were submitted to a biopsy and/or resection of the lesion. The principal brain tumors were meningioma in 30%, astrocytoma in 22%, glioblastoma multiform in 14%, oligodendroglioma in 4% and pituitary adenoma in 4%.
