An emergent magnetic resonance angiography revealed "(...) hyperintense area in T2 and T2 FLAIR in the dorsal lateral aspect of the right bulb that in the diffusion study showed a marked restriction (...)." In the arteriography study, it was identified that "an occlusion of the right vertebral artery was identified in segment V2, after showing progressive reduction and contour irregularity" (Figure 1).
