MR imaging 40 days after the procedure showed signal changes and contrast enhancement in the posterior and right lateral column at T10-11. Circumscribed signal changes in the same areas without contrast enhancement were seen 4 months later. MR imaging was able to show this posterior spinal artery infarct.
