 There is no evidence of diffusion restriction. There are T2/FLAIR hyperintensities in the pons, midbrain, and in the subcortical and periventricular white matter representing chronic ischemic vascular changes.There is a low T1 and high T2 linear hyperintensity that is not seen in FLAIR in the pons representing linear encephalomalacia, likely due to prior hemorrhage.Cannot definitely exclude any chronic hemorrhage due to motion artifact in the susceptibility images.There is prominence of the ventricles and sulci due to age related volume loss. There is no midline shift. Basal cisterns are patent.Vascular flow voids are normal.
1. No evidence for acute intracranial hemorrhage, mass effect, or edema. No acute infarct.2. Subcortical and periventricular white matter, pons, and midbrain hyperintensities on T2/FLAIR representing chronic vascular ischemic changes.3. Linear encephalomalacia in the pons, likely due to prior hemorrhage.
