There is also increased associated vasogenic edema and susceptibility effect. There are unchanged nonspecific punctate foci of T2 hyperintensity in the supratentorial brain. There is no evidence of acute infarct. There is an enlarged partially-empty sella. The ventricles are stable in size and configuration. There is no midline shift or herniation. There is fluid within the right mastoid air cells. The extracranial soft tissues are unremarkable. There are bilateral lens implants.
