 There are postoperative findings related to right parietal craniotomy for resection of a subjacent meningioma with subjacent dural thickening. There are unchanged confluent foci of T2 hyperintensity within the periventricular white matter, right greater left. There are also additional patchy foci of T2 hypertensity throughout the supratentorial white matter that are unchanged as well as unchanged T2 hyperintensity along the resection margins. There is unchanged global volume loss. There is no evidence of acute intracranial hemorrhage, mass, or acute infarct. There is no abnormal intracranial enhancement. 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. There is paranasal sinus mucosal thickening and secretions as well as fluid within the lateral mastoid air cells, right greater then left. There are bilateral lens implants and right-sided axial myopia.
1.Postoperative findings related to right convexity meningioma resection without evidence of recurrence.2.Confluent signal abnormality within the periventricular and deep white matter is unchanged and is most compatible with chronic small vessel ischemic disease.
