Altered mental status. Assess for acute stroke. The study is limited by patient motion, most pronounced for the susceptibility-weighted sequences which are nondiagnostic.There is no acute infarct. Nonspecific T2 FLAIR hyperintense signal in the frontoparietal periventricular white-matter likely reflects chronic microvascular ischemia. Focal T2 FLAIR hyperintensity with increased diffusion is present in the left hemipons, probably represents chronic sequela of prior ischemia. There is mild ex vacuo dilatation of the lateral ventricles and other CSF-containing spaces reflecting underlying parenchymal volume loss. There is no mass-effect, midline shift or brain herniation. Orbits are notable for findings of bilateral lens replacement.
1.Examination is significantly limited by motion especially for susceptibility-weighted imaging.2.No acute infarct. No mass-effect, midline shift or herniation.3.Moderate white-matter abnormality is nonspecific but likely reflect chronic microvascular ischemia. Similarly, focal pontine lesion with increased diffusion probably reflect chronic ischemia.
