A case report of a multi-arterial dural arteriovenous fistula

Dural arteriovenous fistulas are rare intracranial vascular malformations with a propensity for hemorrhage. The Cognard classification system is the most widespread classification system wherein type IIB through V must be promptly treated to avoid the risk of hemorrhage. The case presented herein reports a 71-year-old male presenting with vague non-hemorrhagic neurologic deficits found to have a Cognard type III dural arteriovenous fistula with multiple arterial feeders. Although quite obvious in retrospect, a DAVF can be missed even by an astute radiologist. This should be considered a "never miss" diagnosis as it carries a risk of intracranial hemorrhage and death.
