Dural arteriovenous fistulas are pathologic dural-based fistulas representing about for 10%–15% of all cerebral vascular malformations. These fistulas derive the arterial supply from the meningeal arteries, and their venous drainage is through the dural venous sinuses or the cortical veins.

CT and MR imaging are main tools of the diagnosis, but conventional angiography is the most accurate method for complete diagnosis and classification of DAVFs.
