A case of intractable seizures, originating in the motor cortex, was successfully treated with excision of the seizure focus after precise location of the focus on depth electrode recordings. The depth electrode was placed stereotactically with coordinates from xenon- enhanced CT images. Prior attempts at treating the seizures with ablation of seizure foci had resulted in disappearance of seizure activity on electrocorticography study without cessation of clinical seizures.
