Dural arteriovenous malformations (DAVMs), also known as dural arteriovenous fistulas, are arteriovenous shunts from a dural arterial supply to a dural venous channel, typically supplied by pachymeningeal arteries and located near a major venous sinus.1 The etiology of these lesions is not fully understood. DAVMs in the pediatric population are associated with structural venous abnormalities ,2 but the majority of DAVMs are thought to be acquired. Different etiologies have been implicated in this phenomenon, namely: sinus thrombosis, trauma or surgery.2–6
