69-year-old male with atypical meningioma status post resection and radiation therapy, history of partial seizures, surveillance imaging. Redemonstrated are postoperative findings related to left parietal convexity meningioma resection. Expected evolution of post procedural changes are noted including near total resolution of postoperative blood products, resolution of mass effect, better definition of a postoperative cavity, and only a small residual extradural collection. There remains mild diffuse linear enhancement along the margins of the operative cavity. Previously demonstrated nodular enhancement adjacent to the superior sagittal sinus has not significantly changed, measuring up to 23 mm in maximal dimension (best seen series 1101, image 77/192 as well as series 11 image 137/148), present on prior studies. Mild effacement of the left lateral ventricle has resolved. There are no new abnormal enhancing foci. Mucosal thickening is now present within bilateral ethmoid air cells (right greater than left). Mucosal of thickening is again noted within the inferior maxillary sinuses. The mastoid air cells are clear. Expected vascular flow voids are demonstrated.
