Persistent stapedial artery is a rare vascular anomaly. Imaging identification can prevent unnecessary surgery and aid in planning interventions for this congenital condition.

Area of Science:

  • Vascular Surgery
  • Neuroradiology
  • Otolaryngology

Background:

  • The persistent stapedial artery (PSA) is a rare congenital vascular anomaly.
  • It can manifest as a pulsatile middle ear mass or be an incidental finding during imaging.

Observation:

  • This study presents five cases of PSA.
  • Computed tomography (CT) findings included absence of the ipsilateral foramen spinosum.
  • A soft-tissue prominence near the tympanic segment of the facial nerve was observed.

Findings:

  • Three of the five cases were associated with an aberrant internal carotid artery.
  • CT imaging is crucial for identifying PSA and associated vascular anomalies.

Implications:

  • Accurate imaging identification of PSA can prevent unnecessary surgical exploration.
  • It aids in the precise planning of surgical or endovascular interventions for patients with this anomaly.
