Altered mental status. Evaluate for brain edema or midline shift. A small focus of increased density in the right cerebellar hemisphere is unchanged from the prior CT. Please note that the previously described small enhancing lesions seen on the prior MRI are not visualized on this noncontrast head CT. There is no evidence of intracranial hemorrhage, mass, edema, or midline shift. The ventricles and basal cisterns are normal in size and configuration. The calvaria and skull base are radiographically normal. The visualized paranasal sinuses and mastoid air cells are normally pneumatized.
No acute intracranial abnormality.
