Massive cerebellar infarction caused by spontaneously isolated posterior inferior cerebellar artery dissection: A case report

Figure 2 Findings on magnetic resonance angiography, high-resolution vessel-wall magnetic resonance imaging, and follow-up imaging findings. A: Brain magnetic resonance angiography (MRA) shows no obvious abnormalities; B-D: High-resolution vessel-wall magnetic resonance imaging (HR-VW MRI) reveals a crescent-shaped enhanced lesion in the vascular wall of the posterior inferior cerebellar artery (arrows); E and F: 1.5-month follow-up HR-VW MRI demonstrating complete disappearance of the lesion.
