The hypoglossal canal (HC) is an unusual location of the posterior fossa dural arteriovenous fistula (AVF), which usually occurs in the transverse or sigmoid sinus. Herein, we report a case of HC dural AVF successfully treated with transvenous coil embolization using detachable coils in a 68-year-old woman who presented with headache and left pulsatile tinnitus for 2 months. Brain magnetic resonance imaging (MRI) and cerebral angiography revealed left HC dural AVF. The pulsatile bruit disappeared immediately after the procedure. Follow-up MRI showed complete disappearance of the fistula. Precise localization of the fistula through careful consideration of the anatomy and transvenous coil embolization using a detachable coil can facilitate the treatment for HC dural AVF.
Key words : Hypoglossal canal, Dural Arteriovenous Fistula, Coil Embolization
