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.
