Left ICA angiogram in anteroposterior (A) and lateral (B) views demonstrates the anastomosis between the mandibular artery arising from the petrous ICA and the superior pharyngeal branch of the ascending pharyngeal artery (black arrows) in a patient with a right hypoglossal canal (anterior condyloid) dural arteriovenous fistula. Left vertebral artery angiogram in anteroposterior (C) and lateral (D) views shows arterial feeders from the vertebral arteries through the odontoid arch, arising from the C3 level (white arrows), anastomosing with the hypoglossal branch of the ascending pharyngeal artery (arrowhead).
