Chiari I Malformation and Spinal Cord Ischemia in a Cadaver.

With advanced imaging, the Chiari I malformation (CIM) is more frequently diagnosed than in the past when this entity was identified most commonly at autopsy. Herein, we report the rare case of an adult cadaver found not only to have CIM but also adjacent spinal cord ischemia. This case is discussed in the context of chronic compression of the spinal cord by a CIM and the need for close monitoring of these patients.
