MRI was performed in six cases of spinal arteriovenous malformation (A
VM) and arteriovenous fistula (AVF) before and after embolisation. Int
ramedullary and perimedullary AVMs showed marked vascular enhancement
after embolisation. This was thought to reflect feeding vessel occlusi
on and correlated well with a favourable clinical outcome. In dural AV
Fs, contrast-enhanced studies were essential for the diagnosis, unenha
nced images being nonspecific. After embolisation, enhancement of the
spinal cord was reduced, although one case with a poor outcome showed
persistent enhancement.
