Dural Fistula of the Superior Cerebellar Artery: A Case Report

Abstract

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 65 -year-old male presenting with vague non-hemorrhagic neurologic deficits found to have a Cognard type I right dural superior cerebellar arteriovenous fistula. 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.
