Reason: 3 t scanner pre depth electrode placement History: epilepsy There is redemonstration of asymmetric volume loss involving the left hippocampus with associated increased T2 signal especially along the mid to distal hippocampus. There again may be suggestion of mild diminished size of the left mamillary body.The ventricles and sulci are prominent, consistent with mild age-related volume loss. The basal cisterns remain patent. There is no midline shift or mass effect. A few scattered punctate foci T2 hyperintensity are again seen within the white matter. There is no pathological enhancement. No extra-axial fluid collection is identified.Normal flow-voids are demonstrated in the major intracranial vascular structures. A chronic right lamina papyracea fracture is again noted. There is trace mucosal thickening in ethmoid air cells bilaterally.
1.Redemonstration of findings compatible with left mesial temporal sclerosis.2.Stable nonspecific scattered punctate foci of nonenhancing T2 hyperintensity within the white matter.
