- type II: intramedullary glomus AVM
- type III: juvenile
- type IV: intradural perimedullary (AV fistula)
- sub type I: single arterial supply (ASA), single small fistula, slow ascending perimedullary venous drainage
- sub type II: multiple arterial supply (ASA and PSA), multiple medium fistulae, slow ascending perimedullary venous drainage
