Meningioma, preoperative evaluation. Examination is limited to sequences for operative planning. Again seen are postoperative findings related to parietal craniotomy. As measured before, there is interval increase in size of the posterior falcine meningioma compared to 10/8/2013, which 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 consistent with gliosis with possible some vasogenic edema. Encephalomalacia in the left parietal occipital region again seen. Obliteration of the posterior superior sagittal sinus again seen. The ventricles are unchanged in size and configuration without hydrocephalus. There is no midline shift or herniation. The posterior superior sagittal sinus is obliterated. There is a partially-empty sella. Again seen is diffuse right mastoid and right middle ear opacification. Empty sella again seen.
Examination for operative planning demonstrating increase in size of the parasagittal meningioma compared to 10/8/2013 but not significantly changed since 2/9/2015.
