32 years, Male, epilepsy. Laser ablation. Prior depth electrodes have been removed. Placement of laser fiber via right posterior parietal approach is seen which terminates in the right anterior medial temporal lobe along the dura. There is extensive peripheral enhancement involving the right medial temporal lobe reflecting the ablation zone.Multiple prior right-sided burr whole craniotomies and evidence of prior depth electrodes is noted. There is no evidence of intracranial mass effect or herniation. Subcortical band heterotopia again noted. Ventricles remain normal in size.
Extensive peripheral enhancement is seen in the right medial temporal lobe likely reflecting laser ablation zone.
