Episodic dizziness and vertigo. No restricted diffusion to suggest acute ischemia. No intracranial hemorrhage. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. Few scattered 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. Minimal mucosal thickening is seen involving the anterior ethmoid sinuses. Paranasal sinuses and mastoid cells are otherwise clear. Bone marrow signal and extracranial soft tissues are within normal limits.
MRI of the brain is within normal limits for age. No evidence of acute infarct, intracranial mass, or mass effect.
