Pre and post enhanced head. Nonenhanced head CT portion of the study demonstrate significant prominence of cerebellar and vermian folia and symmetrical bilateral prominence of cortical sulci and ventricular system for patients stated age of 55. Findings are consistent with underlying parenchymal volume loss. There is no definitive foci of abnormal parenchymal density. Postcontrast images demonstrate no detectable abnormal enhancement of brain parenchyma or the leptomeninges. The intracranial venous sinuses demonstrate normal density and normal pattern of enhancement. Unremarkable images through the orbits and without detectable abnormal enhancement. The paranasal sinuses and bilateral mastoid air cells and middle ear cavities remain well pneumatized.
