Preoperative planning for seizures. Limited planning MRI demonstrates continued evolution of laser ablation effects in the right parietal lobe with decreased enhancement in the ablation zone. There are also postoperative findings related to partial right temporal lobe lobectomy with confluent T2 hyperintensity along the surgical margins. There is no mass effect. The ventricles and basal cisterns are unchanged in size and configuration. There are subcentimeter left choroid plexus xanthogranulomas. There is no midline shift or herniation. The major cerebral flow voids are intact. There is a small encephalocele through the right occipital burr hole. There is a fluid level in the left maxillary sinus.
1. Examination is obtained for operative planning. Continued evolution of laser ablation effects in the right parietal lobe.2. Postoperative findings related to partial right temporal lobe lobectomy with probable gliosis along the surgical margins.3. Small encephalocele again seen through the right occipital burr hole.
