 Brain parenchymal morphology is within normal limits. There are scattered punctate foci and confluent areas of abnormal T2/FLAIR hyperintensity within the periventricular and subcortical white matter. No edema is detected. No definite diffusion-weighted abnormality. Geographic area of mild diffusion hyperintensity within the left frontal lobe white matter without corresponding abnormal ADC signal is favored to reflect T2 shine through artifact. There is no evidence to suggest intracranial hemorrhage or any abnormal extra-axial fluid collection. There is no pathological intracranial enhancement. The ventricles are prominent compatible with age-related volume loss.
1. No evidence of acute ischemia. No specific findings to account for the patient's visual changes.2. Moderate chronic small vessel ischemic changes.
