Figure S2. Coronal 3D-T1WI of ICA in the first and the second episode. (A): Image in the first episode. The vessel walls might be thicker over the left entire ICA compared to the right, but it was not clear. (PDF 322 kb) (B): Image in the second episode. Stenosis became severe, especially in the distal portion of the left ICA. High intensity lesion on T1 W1 in the distal portion of the left ICA (arrow) was observed.

Moreover, vasculitis can cause aortic dissection, for example, Takayasu arteritis
