Implanta？？o estereotáxica de eletrodos profundos por ressonancia magnética para cirurgia de epilepsia

we present the case of a 40-year-old woman with refractory epilepsy since aged 18, who was submitted to video-eeg monitoring with intracerebral depth electrodes. the clinical history and examination, magnetic resonance image (mri), video-eeg and neuropsychological study did not allow the determination of the cerebral onset of epileptic seizures. depth electrodes inserted by mri-guided stereotaxis allowed the recording of the epileptic activity and thus showed quite accurately the area of the brain to be surgically resected. she underwent a right anterior temporal lobectomy with amygdalohippocampectomy. the immediate postoperative period was uneventful and she is without epileptic seizures after three months of follow-up. the average pre-operative free-seizure period was two weeks. to our knowledge, this is the first stereotactic surgery for insertion of depth intracerebral electrodes in epilepsy in brazil.
