Axial reconstructed images of rotational angiogram of the left external carotid artery show the fistulous pouch (white arrows) draining through the posterior condylar vein (PCV) into the posterior cervical vein inferiorly and the occipital sinus (OS) posterosuperiorly. The occipital sinus and the posterior condylar vein form a common trunk (arrowheads) that joins into the sigmoid sinus (SS). H. Kiyosue et al.
