Figure 2: A diffusion-weighted magnetic resonance image revealed an area containing a high-intensity signal in the left cerebellar hemisphere (a) The depiction of the right posterior inferior cerebellar artery was poor on the brain magnetic resonance angiography (b). Computed tomography angiography revealed a pearl-string lesion at the orifice of the right posterior inferior cerebellar artery (c, black circle). A repeat computed tomography angiography showed improvement in the stenosis of the posterior inferior cerebellar artery distal to the dissection (d, black circle)
