Male, 21 years old, history of epilepsy, planning for laser fiber placement Multiple intracranial electrodes are redemonstrated in stable position. This includes two which traverse the right frontal lobe, three which traverse the right temporal lobe from a lateral approach, one which traverses the right medial temporal lobe from a posterior approach, and one which traverses the left medial temporal lobe from a posterior approach.Aside from mild dural enhancement which is likely reactive to instrumentation, no pathologic intracranial enhancement is seen. No evidence of significant parenchymal edema or mass effect is detected. The ventricular system is stable and normal in size.
Selected sequences for surgical planning are provided which redemonstrate multiple intracranial electrodes in stable position.
