No abnormal parenchymal or meningeal enhancement. No restricted diffusion to suggest acute ischemia. No intracranial hemorrhage. The ventricles are within normal limits in size with cavum lucidum and cavum vergae incidentally noted. A few foci of T2/FLAIR hyperintensity are seen in the bilateral subcortical and periventricular white matter, which are nonspecific, but compatible with mild age-related white matter changes. Brain parenchyma is otherwise unremarkable for age. Major flow-voids are preserved.Sella and orbits are grossly within normal limits. Paranasal sinuses and mastoid cells are clear. Bone marrow signal and extracranial soft tissues are within normal limits.
