STEREOTAXIC LOCATION AND EXCISION OF SEIZURE FOCUS WITH XENON-ENHANCED CT

A case of intractable seizures, originating in the motor cortex, was s uccessfully treated with excision of the seizure focus after precise l ocation of the focus on depth electrode recordings. The depth electrod e was placed stereotactically with coordinates from xenon-enhanced CT images. Prior attempts at treating the seizures with ablation of seizu re foci had resulted in disappearance of seizure activity on electroco rticography study without cessation of clinical seizures.
