title: Dural arteriovenous fistula in the falx cerebri treated with transarterial embolization using n-butyl cyanoacrylate.
abstract: BACKGROUND
  A dural arteriovenous fistula in the falx cerebri is a relatively rare lesion, with only two cases reported till date. One was treated with direct surgery, and the other was followed-up conservatively. Advances in catheter design and embolic materials have made safe and curative transarterial embolization of dural arteriovenous fistulas possible in the current era.
  
  
  METHODS
  We describe a 67-year-old man with left putaminal hemorrhage who was diagnosed with an arteriovenous fistula in the anterior part of the falx cerebri that was treated with curative transarterial glue embolization through the middle meningeal artery by using n-butyl cyanoacrylate.
  
  
  CONCLUSIONS
  Although the procedure was safely performed, understanding the potential risks of the migration of embolic materials into the ophthalmic and anterior cerebral artery system is mandatory.
