Headache and history of meningioma. There are postoperative findings related to parietal craniotomy. There is interval increase in size of the posterior falcine meningioma, which now measures 25 x 43 x 28 mm, previously 19 x 34 x 25 mm. However, there is no significant interval change in the extent of confluent T2 hyperintensity in the bilateral posterior cerebral hemisphere white matter, which likely represents vasogenic edema. There is also unchanged left parieto-occipital encephalomalacia. There are unchanged foci of susceptibility effect in the brain parenchyma surrounding the tumor, which may represent chronic blood products. The ventricles are unchanged in size and configuration. There is no midline shift or herniation. The posterior superior sagittal sinus is obliterated. There is a partially-empty sella. There is mild mucosal thickening in the left sphenoid sinus. There is new right tympanomastoid fluid.
