[Clinical and angiographic aspects of medullary angiomas].

The authors present six personal cases of medullary angiomas: three cases of retromedullary, one of intramedullary and two of intra-retromedullary vascular malformations. One of two last cases was associated with a paravertebral arteriovenous malformation. The neuroradiologic investigations include a water-soluble myelography, with hypocicloidal tomography, and spinal cord selective angiography. The latter present many advantages of the aortography, for feeding arteries visualization, but the site of the shunt inside the intervertebral foramen can be localized only by angiotomography. In our cases neurological complications or clinical worsening were not found.
