76 years, Male, left upper extremity numbness and tingling, history of previous CVA. No restricted diffusion to suggest acute ischemia is definitively appreciated. There is subtle punctate focus of diffusion hyperintensity involving the left parietal subcortical region, axial diffusion images 259, without corresponding T2/FLAIR hyperintensity and may be artifactual. No intracranial hemorrhage. No intracranial mass or mass-effect. The ventricles are within normal limits in size for age.Several foci of T2/FLAIR hyperintensity are seen in the bilateral subcortical and periventricular white matter, which are nonspecific, but compatible with mild chronic small vessel ischemic disease and similar to prior study from 10/18/2007. Brain parenchyma is otherwise unremarkable for age. Paranasal sinuses and mastoid air cells are clear. Bilateral lens implants. Calvarium and extracranial soft tissues are grossly unremarkable.
1. No definite evidence of acute infarct. Subtle punctate focus of diffusion hyperintensity in the left parietal lobe may be artifactual.2. Mild chronic small vessel ischemic changes which are similar to prior study from 10/18/2007.
