53 year-old woman with altered mental status. Unsure of baseline. Otherwise stable. There are diffuse regions of hypoattenuation consistent with prior infarct throughout the cerebral cortex. There are diffuse areas of encephalomalacia most pronounced in the left occipital lobe. Extensive periventricular hypoattenuating regions consistent with age indeterminate, small vessel ischemic disease. These findings are unchanged from the prior study dated 5/1/2008. If acute stroke is a clinical concern, recommend MRI. The ventricles are unchanged in size from the prior study. The 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.
1. Stable head CT with extensive ischemic changes. If acute stroke is a clinical concern, recommend MRI.
