Epilepsy; planning for laser fiber placement. There has been interval removal of several transoccipital and transtemporal depth electrodes positioned from the right temporal lobe region with patchy enhancement along portions of the surgical tracks. There is also interval laser ablation of the right medial temporal lobe. There is no evidence of any substantial intracranial hemorrhage. The ventricles are unchanged in size and configuration. There is no midline shift or herniation. There are postoperative changes in the skull and scalp.
Operative-guidance MRI shows expected interval laser ablation effects in the medial right temporal lobe region.
