Central nervous system vascular malformations are abnormalities of blood vessels in your brain or spinal cord and their membranes.

Central nervous system vascular malformations are rare and include:

  • Arteriovenous malformations. A brain (intracranial) arteriovenous malformation is an abnormal tangle of blood vessels in your brain.
  • Capillary telangiectasias. Capillary telangiectasias are small dilated blood vessels (capillaries).
  • Cavernous malformations. Cavernous malformations are abnormally formed blood vessels in your brain or spinal cord that have the appearance of a mulberry.
  • Dural arteriovenous fistulas. Dural arteriovenous fistulas are abnormal connections between arteries and the tough covering over the brain or spinal cord (dura) and a draining vein.
  • Spinal arteriovenous malformations. A spinal arteriovenous malformation is an abnormal tangle of blood vessels on, in or near your spinal cord.
  • Venous malformations. Venous malformations are abnormally enlarged veins in your brain or spinal cord.
