Volume rendering reconstruction (A) and parasaggital cut of a DynaCT dataset (B) show multiple hypertrophied circumferential pontine arteries (arrows) involved as feeders in the supply of a mesencephalic AVM (*). Compared with the volume rendering reconstructions A and B, 2k DSA images of the same patient in standard projections, C and D, show fewer circumferential arteries (arrows) and those that are displayed are less well visualized.
