Meningioma, 6 month follow up. There is no significant interval change in size of the extra-axial enhancing left lateral skull base mass centered along the left petrous apex with extension into the cavernous sinus left prepontine cistern and along the left tentorial leaflet with associated hyperostosis and permeation of tumor into the underlying skull, as well as encasement of the left cavernous carotid artery, and mass effect with vasogenic edema in the left temporal lobe. There is also mass effect upon the left brainstem. There is no evidence of acute intracranial hemorrhage or acute infarction. The ventricles are normal in size and configuration. There is no significant midline shift. There is staphylomatous deformity of the bilateral globes. There is mild high T2 signal within the left mastoid air cells suggestive of fluid or mucosal thickening. There appears to be filler material within the bilateral nasolabial folds.
