Findings from MRI and histological examination of spinal cord ischemia. (A) Sagittal T2-weighted image of the thoracic spinal cord demonstrating a pronounced hyperintensity from the seventh to the twelfth thoracic vertebra. Sagittal (B) and axial (C) T2-weighted turbo spin-echo images of the brain displaying right-sided pontine infarction which is marked by a white arrow. Hematoxylin and eosin (H&E) staining of myelon biopsy displaying necrotic central nervous system tissue with macrophages. Original magnification 20x (D) and 40x (E).

T2 hyperintense lesion of the thoracic spinal cord that did not enhance after gadolinium administration ( Figure 1A ). The diffusion-weighted imaging showed no signal loss in the apparent diffusion coefficient map. The histological examination revealed necrotic tissue consistent with previous spinal cord ischemia ( Figures 1D, E ). Two years onward, the patient suffered from a pontine infarction ( Figures 1B, C ) with vertigo and weakness of the left arm, and one month later, a transient ischemic attack with latent right-sided hemiparesis occurred.
