Last revised by Mikesh Mistry on 7 Jul 2022

Cerebrovascular malformations are vascular malformations related to the vessels that supply the brain and other cranial structures.


Over the years, cerebral vascular malformations have been classified in a variety of ways by many authors, often on the basis of the presence or absence of arteriovenous shunting, histopathological features or demographics of affected individuals 4.

High or low flow
Presence or absence of shunting

Some lesions are only encountered in specific age-groups, usually within early childhood.  

  • in utero: pial high flow AVF, VGAM, DSM
  • neonate: VGAM, pial high flow AVF, DSM
  • infant: VGAM, pial AVMs, cavernous angiomas, aneurysm
  • child: pial AVM (nidal > fistulous), aneurysm, cavernous venous malformation (cavernoma), dural AVF
