Figure e-2 A B C D E F Legend . Others components than white matter changes of cerebral small vessel disease. The axial gradient-echo images demonstrate a microbleed in right lenticular nucleus of patient A.III.1 (A) and in left center semi-ovale of patient A.III.3 (B). The axial T2-WI shows lacunar infarcts in patients A.III.1 (C, cerebellar hemisphere) and A.III.3 (D, center semi-ovale). The T2 weighted images on axial slice in patient A.III.1 (E) and on sagittal slice in patient B.III.2 (F) show dilated perivascular spaces of basal ganglia and center semi-ovale respectively. sonia.alamowitch@tnn.aphp.fr
