Reason: History of headache, evaluate for intracranial process or infection. The ventricles and sulci are prominent, consistent with mild age-related volume loss. The subarachnoid spaces remain somewhat more prominent anteriorly. The basal cisterns are patent. There is no midline shift or mass effect. Scattered punctate foci of increased T2/FLAIR signal within the subcortical and periventricular white matter are nonspecific but compatible with chronic small vessel ischemic changes, not significantly changed. Multiple small chronic cortical infarcts are seen within the cerebellum, also appearing similar to prior. There is no diffusion abnormality. No extra-axial fluid collection is identified. Normal flow-voids are demonstrated in the major intracranial vascular structures. There is a partially empty sella, not significantly changed.There is minimal patchy opacification within the paranasal sinuses. There is mild rightward nasal septal deviation.
1.No acute ischemia or other acute intracranial abnormality.2.Mild chronic small vessel and cerebellar cortical ischemic lesions.
