Clinical question: Memory loss with vascular risk factors. Signs and symptoms: As above. Nonenhanced brain MRI:Negative diffusion weighted images.Examination demonstrate periventricular and subcortical foci of FLAIR hyperintensity in bilateral cerebral hemispheres. Minimal similar signal changes are also present in bilateral basal ganglia and pons. Although nonspecific considering patient's stated age of 79 this appearance is often result of microvascular ischemic changes. The findings are not associated with any hemorrhagic changes.There is generalized prominence of cortical sulci for patient of stated age of 79. The ventricular system are mildly prominent however likely within normal for stated age.Signal void of major intracranial arterial branches are identified.The signal intensity of intracranial venous sinuses are normal.Unremarkable images through the orbits, calvarium, soft tissues of the scalp and paranasal sinuses.
1.No diffusion-weighted abnormalities.2.Changes suggestive of chronic nonhemorrhagic small vessel ischemic strokes of mild degree.3.Generalized prominence of cerebral cortical sulci for patient's stated age as detailed.
