Meningioma resection surveillance. There are postoperative findings related to right parafalcine meningioma resection with unchanged encephalomalacia in the underlying right parietal lobe. However, there is interval increase in size of a nodular enhancement in the surgical bed along the right aspect of the posterior superior sagittal sinus, which measures 16 x 18 mm in axial cross-section, previously 12 x 13 mm. The tumor protrudes in to the subgaleal space through th calvarial defect. There is no evidence of intracranial hemorrhage or acute infarct. There is unchanged patchy nonspecific scattered cerebral white matter T2 hyperintensity beyond the region of the surgical bed. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. There are bilateral lens implants. There are persistent secretions in the left frontal sinus.
