The distribution of cerebral microbleeds in vertebrobasilar dolichoectasia were noted according to the to the maps by Tatu et al.
[27,28] Supratentorial: Anterior circulation (blue), and posterior circulation including occipital lobe (yellow), thalamus (red), splenium (green), and hippocampus (pink). Infratentorial: Brainstem, including mesencephalon (brown), pons (orange), and medulla oblongata (turquoise), and cerebellum (violet).
