History of epilepsy status post laser ablation of the left hippocampus. There are postoperative findings related to left occipital approach laser ablation of the left hippocampus, where there are persistent punctate foci of high T2 signal and enhancement. The rest of the brain parenchyma appears unremarkable. There are also postoperative findings related to left temporal craniotomy and left frontal burr hole, with diffuse enhancement in the overlying scalp soft tissues. There is no evidence of acute infarct. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits are grossly unremarkable. There is a small left maxillary sinus retention cyst.
