A case of dural arteriovenous fistula with retrograde intracranial venous flow.

PRESENTATION: Dural arteriovenous fistulae are relatively rare lesions which can present a variety of different symptoms ranging from tinnitus to devastating intracranial hemorrhage. For those fistulae that require treatment, therapy is available in a wide range of options. We describe the case of a 60-year old patient who presented with a right occipital lesion presumably secondary to a dural arteriovenous fistula of the right transverse-sigmoid junction. The patient underwent successful endovascular treatment of the fistula. DISCUSSION: The participants in our discussion present their thoughts on how to evaluate and when and how to treat dural arteriovenous fistulae.
