  • Title: The persistent stapedial artery.
    Author: Silbergleit R, Quint DJ, Mehta BA, Patel SC, Metes JJ, Noujaim SE.
    Journal: AJNR Am J Neuroradiol; 2000 Mar; 21(3):572-7. PubMed ID: 10730654.
    Abstract:
    The persistent stapedial artery is a rare congenital vascular anomaly that may present as a pulsatile middle ear mass or that may appear as an incidental finding. Five cases of persistent stapedial artery are presented. The CT findings include the absence of the ipsilateral foramen spinosum and a soft-tissue prominence in the region of the tympanic segment of the facial nerve. Three cases were associated with an aberrant internal carotid artery. Imaging identification of this variant may obviate unnecessary surgery and may help in planning surgical or endovascular interventions.
