B, Anteroposterior-view angiogram of the vertebral artery shows a second AVM (micro AVM) (arrow), involving the left occipital cortex, fed by a branch of the posterior cerebral artery and draining into a single vein (open arrows).

C, Lateral-view angiogram shows another micro AVM (arrow) involving the right occipital lobe cortex supplied by a parieto-occipital artery with a single draining vein (open arrows).
