 There is no territorially restricted diffusion to suggest acute ischemic infarction. There are unchanged postoperative findings related to resection of left posterior temporal and parietal lobe mass. There is unchanged nonenhancing mild T2 hyperintense signal abnormality surrounding the resection cavity. There is mild ex vacuo dilatation of the trigone of the left lateral ventricle. There is no suspicious intracranial enhancement. There are numerous punctate gradient echo hypointense signal abnormalities in the bilateral cerebral hemispheres, surgical cavity, and brainstem appearing similar to the prior study and which may be posttreatment related. The major cerebral flow voids are intact. There is minimal tonsillar ectopia appearing similar to prior study. The orbits and paranasal sinuses appear unremarkable. The calvarium and extracranial soft tissues are within normal limits.
No recurrent intracranial tumor.
