Bilateral resective epilepsy surgery in a child with tuberous sclerosis: case report.
OBJECTIVE
Surgical intervention can reduce the burden of seizures in selected patients with tuberous sclerosis and medically refractory epilepsy.


METHODS
A child presented with tuberous sclerosis and severe epilepsy beginning in the first month of life and delayed development before 1 year of age. Video-electroencephalographic monitoring at the age of 1 year revealed a left temporal seizure focus. Repeat videoelectroencephalography at 2 years of age revealed a right posterior quadrant seizure focus. Bilateral subdural electrodes were placed, confirming independent seizure onsets from the right parietal area (overlying a tuber) and prominent interictal activity over the left superior temporal region.


METHODS
The right parietal focus was resected, and electrodes were maintained over the left temporal focus. After right parietal resection, ictal discharges were recorded over the left temporal region; a corticectomy was performed 2 days later. No tonicoclonic or complex partial seizures have occurred during a follow-up period of more than 24 months. Simple partial motor seizures involving the right foot have been reduced by more than 80%, and other simple partial seizures have been eliminated. Postoperatively, there has been marked improvement in the patient's cognitive and motor developmental status.


CONCLUSIONS
In selected patients with bilateral seizure foci involving separate lobes, aggressive bilateral surgery can be safe and effective.
