case_images: MRI revealed no abnormality, such as ossification, stenosis, a mass, or intramedullary signal changes (Figure 1).

case_images: CT revealed a thrombosed aortic dissection in the descending aorta (Stanford type B) and severe arteriosclerosis (Figure 2).
case_images: Diffusion-weighted MRI slightly showing abnormality on day 5 (a). Signal changes could be seen a little more clearly on a black and white inverted image (b).

case_images: We then performed diffusion MRI, which showed the abnormality more clearly (Figure 4).
case_images: Enhanced CT showing aortic dissection with aortic aneurysm in the descending aorta.
