Eleven cases of spinal ependymomas were studied by angiography. In four cases there was a tumoral blush, and in five cases, indirect signs of a spinal tumor. Although direct opacification of some caudal ependymomas is of great value, the main interest of spinal angiography is in the differential diagnosis with arterio-venous malformations, when there is a spinal S.A.H. or when there are abnormal vascular markings on the myelogram.
