We present a 43-year-old male patient who has bilateral spontaneous idiopathic Vertebral Arterio Venous Fistula (VAVF) which is rarely seen. The importance of our case is that the third case of bilateral VAVF which was reported in the literature and the first case of spontaneously developed with uncertain etiology. Due to risk factors, bilateral and sub axial cases are difficult to treat and their surgical complications can be lifethreatening and sometimes unsolvable.
