Target Audience:
Intended for neuroradiologists and neuroradiology trainees with varying degrees of experience.

Learning Objectives:
Describe the cross-sectional imaging findings of dural arteriovenous fistulas and correlate with angiographic imaging.

Abstract
Intracranial dural arteriovenous fistulas represent vascular malformations that can result in intracranial hemorrhage or neurologic injury, or that can result in clinical signs and symptoms related to their intracranial location. Cross-sectional imaging is often performed for the initial evaluation of these potential clinical presentations and may represent the first opportunity to make a diagnosis. Although most intracranial vascular malformations can be readily identified by a limited number of distinct imaging appearances, intracranial dural arteriovenous fistulas may demonstrate multiple, more clandestine, cross-sectional imaging patterns. Therefore, knowledge of the possible imaging patterns is critically important to detect the presence of an intracranial dural arteriovenous fistula. The purpose of this article was to demonstrate the key cross-sectional patterns of intracranial dural arteriovenous fistulas with angiographic correlation to improve the understanding and diagnosis of intracranial dural arteriovenous fistulas.
