ANGIOGRAPHY OF EPENDYMOMAS OF THE SPINAL CORD AND FILUM TERMINALE

GIOVANNI DI CHIRO M.D.1 and LOUIS WENER M.D.2

1 Section on Neuroradiology, National Institute of Neurological Diseases and Stroke, National Institutes of Health, Bethesda, Maryland.
2 Department of Radiology, Cafritz Memorial Hospital, Washington, D.C.

The angiographic findings in 4 cases of spinal cord ependymoma, three of the myxopapillary type, are reported.

Enlargement and displacement of the anterior spinal artery, striking visualization of the anastomotic loop(s) around the conus, and, in 1 case, pathologic vessels have been observed.

The findings, although not pathognomonic, are significant, particularly considering that they were not evident in 4 other patients with cord gliomas other than ependymomas.
