Presurgical epilepsy evaluation: left temporal lobe epilepsy. There is redemonstration of abnormal signal and volume loss involving the left hippocampal head. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The ventricles and basal cisterns are unchanged in size and configuration, with an asymmetrically larger left lateral ventricle. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
