69-year-old male with altered mental status. There is no evidence of intracranial hemorrhage, mass or edema. Hypodensities in periventricular white matter most consistent with small vessel ischemic disease, which were present on prior MRI.The ventricles and basal cisterns are normal in size and configuration.Several small, round bony excrescences are seen arising from outer table of skull, of unclear etiology but doubtful clinical significance (sagittal series 80475, image 26). The calvaria and skull base are otherwise radiographically normal. The visualized paranasal sinuses and mastoid air cells are normally pneumatized.
No acute intracranial abnormality.
