Clinical question: Memory loss for 2 years. Signs and symptoms: As above. Nonenhanced brain MRI:No diffusion-weighted abnormalities.Examination demonstrate patchy periventricular and to a lesser degree subcortical confluent foci of FLAIR hyperintensity in bilateral cerebral hemispheres. Minimal similar signal changes in bilateral basal ganglia and pons is detected. There is no associated susceptibility signal changes with the findings which are highly suggestive of chronic small vessel ischemic strokes of mild degree.There is also mild generalized prominence of cortical sulci and the supratentorial ventricular system for patient's stated age of 61.The signal void of major intracranial arterial branches are identified.The signal intensity of intracranial venous sinuses are within normal.Unremarkable images through the orbits, paranasal sinuses and mastoid air cells.
1.No acute intracranial findings.2.Findings suggestive of mild chronic nonhemorrhagic small vessel ischemic strokes.3.Generalized mild prominence of cortical sulci and supratentorial ventricles for stated age of 61.
