73-year-old female with right facial numbness. Evaluate for ischemia. There is no evidence of intracranial hemorrhage, mass or edema. Focus of decreased attenuation is present in a wedge-shaped distribution in the right posterior cerebellum reflecting prior infarct in a posterior inferior cerebellar artery distribution. There are multifocal regions of low attenuation throughout the subcortical and deep white matter periventricular distribution, nonspecific, however most likely representing small vessel ischemic disease, age indeterminate. If there is clinical concern for acute ischemia, an MRI may be considered.No areas of acute cortical ischemia identified.The ventricles and basal cisterns are normal in size and configuration.The calvaria and skull base are radiographically normal. There is near complete opacification of the left maxillary sinus which represents a retention cyst, unchanged. The remaining visualized paranasal sinuses and mastoid air cells are normally pneumatized.
