30 year old male patient with seizures. Limited sequences obtained for treatment planning and intraoperative evaluation. Laser fiber is seen extending from a left occipital burr hole to the medial left temporal lobe in the region of the hippocampus. Within the region of the left hippocampus and portions of the left amygdala, there is a 2.2 x 1.2 cm peripherally enhancing ablation zone (image 71, series 1201). Additional left sided burr holes are also noted. The ventricles and basal cisterns are stable in size and configuration. There is no midline shift or herniation. The orbits and paranasal sinuses are grossly unremarkable.
Expected post-surgical changes of repeat laser ablation of the left hippocampus and portion of the amygdala.
