Massive Infarction of Spinal Cord and Vertebral Bodies as a Complication of Dissecting Aneurysm of the Aorta

A case of spinal cord and vertebral body necrosis as a complication of dissecting aneurysm of the aorta has been presented. Previous report of vertebral body necrosis complicating this entity could not be found. The incidence of intercostal and lumbar artery involvement in this condition is not known; a disparity appears between the incidence of involvement and necrosis of structures supplied by them. Factors believed to be important in assessing the significance of involvement of these vessels are mentioned. All cases of dissecting aneurysm in which there are neurologic signs should have thorough study of the spinal cord and vertebral bodies if they come to autopsy.
