Ependymoma is a kind of gliomas that is originated from ependymal cells of the cerebellar ventricles and the central canal of the spinal cord.
It rarely metastatizes to some organs and destructs the vertebral bodies, though most of the Ependymoma are histologically benign.
We experienced one case of Myxopapillary Ependymoma double-located in Cauda Equina with destruction of Sacrum. We performed wide laminectomy of lumber spine and Sacrum, and removed the tumor. C. U. S. A. (Cavitron Ultrasonic Surgical Aspirator) helped us to remove the tumor macroscopically almost perfectly from inside of the capsule.
