92 year-old male with altered mental status, found down. There is no evidence of intracranial hemorrhage, mass or edema. Multifocal regions of patchy hypoattenuation are present in a subcortical and periventricular deep white matter distribution, nonspecific; however, most likely represent small vessel ischemic disease, age indeterminate. If there is clinical concern for acute ischemia, MRI may be considered.The ventricles and basal cisterns are mildly enlarged secondary to diffuse volume loss.The calvaria and skull base are radiographically normal. The visualized paranasal sinuses and mastoid air cells are normally pneumatized.
1. No acute intracranial abnormalities.2. Multifocal regions of patchy hypoattenuation compatible with small vessel ischemic disease, age indeterminate. If there is clinical concern for acute ischemia an MRI may be considered.
