Intracranial arterial dissection. Magnetic resonance angiography (a) showed luminal stenosis in basilar artery (arrow). Diffusion-weighted imaging showed new pontine infarction due to perforator occlusion (b, arrow). T1- (c, arrow) and proton density- (d, arrow) weighted vessel wall image showed intimal flap and double lumen obviously (magnified view in the inset). MRA: Magnetic resonance angiography; DWI: Diffusion weighted imaging; VWI: Vessel wall imagin; PD VWI: Proton density VWI.
