Multiple infra and supratentorial white matter hyperintensities have a predominantly periventricular distribution, also involving the callososeptal interface, with a few subcortical and in a juxta-cortical distribution. No areas of abnormal diffusion restriction or abnormal contrast enhancement to suggest active lesions. The brain volume is within the normal range for the patient's age group. Ventricles and basal cisterns are normal. An incidental tiny developmental venous anomaly in the right cerebellar hemisphere.
