The authors reported a case of a dural arteriovenous fistula (DAVF) in the left transverse‐sigmoid sinus, in which 3‐dimensional computed tomography (CT) angiograms (3D‐CTAs) by a 64‐section multidetector row CT scanner were useful for its diagnosis and treatment. The DAVF in the left transverse‐sigmoid sinus appeared on the digital subtraction angiogram. 3D‐CTAs were obtained by a 64‐section multidetector row CT scanner before an endovascular treatment. The feeders and draining veins of the DAVF were clearly demonstrated on the 3D‐CTAs, which clarified the relationship between the normal dural sinuses and DAVF. The DAVF was successfully treated with endovascular surgery, a transvenous embolization through the mastoid emissary vein, which was easily detected by using the 3D‐CTA, showing both the subcutaneous vein and calvalium. 3D‐CTAs by a 64‐section multidetector row CT scanner are useful for both diagnosis and treatment of DAVFs.
