A: Lateral projection of left carotid arteriogram shows dilated afferent artery (solid arrow) feeding the right hemispheric parietal AVM (open arrow). B: Right carotid injection fills a second, more posteriorly located, parietooccipital AVM (open arrow), which drains immediately to markedly dilated cortical veins (curved arrow).
