 There is no abnormal enhancement, acute infarct, mass effect or midline shift. There is an unchanged right frontal calvarial burr hole with persistent cystic encephalomalacia in the right superior frontal gyrus and nonspecific confluent surrounding T2 hyperintensity extending toward the right periventricular white matter, similar to prior examinations. There is unchanged minimal dural thickening and enhancement subjacent to the burr hole. There is also nonspecific periventricular and subcortical white matter T2 hyperintense signal abnormality elsewhere which is also similar in appearance representing combination of small vessel ischemic changes and posttreatment changes. There is a tiny unchanged chronic left cerebellar hemisphere infarct.
Stable posttreatment findings with no evidence of tumor recurrence.
