AbstractDigital subtraction angiography (DSA) is the best method of evaluating carotid cavernous fistulas (CCF). DSA, however, has the disadvantage of being an invasive procedure. Computerized tomography (CT) angiography which is noninvasive, have been shown to provide more information about the size and location of fistulas. As a new method, Bone-Subtraction CT Angiography (BSCTA), than conventional CT angiography, is a method that improves the detection and interpretation of vascular lesions near to the cavernous segment of carotid artery. In this case report, we report a case of a dural carotico-cavernous fistula (CCF), appearances of pre and postembolization BSCTA images, confirmed by on DSA. As far as we know, CCF demonstrated by BSCTA has not been reported yet.
