ABSTRACT: This study aims to explore the utility of angiographic computed tomography (CT) in the diagnosis and treatment of neurovascular pathologies in the vicinity of cranial base. Two cases of cranial base dural arteriovenous fistula, one internal carotid pseudoaneurysm and one PICA aneurysm were demonstrated utilizing the angiographic CT for obtaining significant image details on the relative location of the diseases against the neighboring bony structure. An angiography suite outfitted with conventional DSA and rotational volume cone-beam was used, angiographic CT images being concomitantly produced together with the routine angiographic modalities. By virtue of the angiographic CT images integrating the selective angiography and reconstructed cranial base tomography, we succeeded in getting significant information on the relative location of various vascular diseases to the skull base, greatly facilitating the diagnosis and treatment procedures.
