Nonenhanced head. There is no detectable acute intracranial process. CT however is insensitive for early detection of acute nonhemorrhagic ischemic strokes. There is prominence of cortical sulci which may be at the upper limits of normal for age however possibility of underlying parenchymal volume loss should also be considered. This appearance remains similar to prior exam from 2014. Ventricular system are within normal size for age and with maintained midline. CSF spaces remain widely patent. The gray-white matter differentiation is preserved. Unremarkable calvarium, orbits, paranasal sinuses and mastoid air cells.
