54 years, Female, dizziness and giddiness. Evaluate for ischemia. There is restricted diffusion within the right inferior medial cerebellum with correlative ADC hypointensity and T2 hyperintensity, consistent with acute infarction. No intracranial hemorrhage is evident by susceptibility weighted imaging. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. There are a few punctate foci of T2/FLAIR hyperintensity are seen in the right frontal and left parietal subcortical white matter, which are nonspecific, but most compatible with chronic small vessel ischemic changes. Major flow-voids are preservedSella and orbits are within normal limits. Paranasal sinuses and mastoid cells are clear. Bone marrow signal and extracranial soft tissues are within normal limits.
1.Acute infarction within the right posterior inferior cerebellar artery territory.2.Nonspecific T2 hyperintense foci within the subcortical white matter, most likely secondary to chronic small vessel ischemic disease.
