Area of Science:

Vascular Surgery
Neuroanatomy
Embryology

Background:

Vertebral artery fenestration is a rare congenital vascular anomaly.
It most commonly affects the extracranial segments of the vertebral artery.
This anomaly arises during vertebral artery embryological development.

Observation:

This report details a case of intracranial vertebral artery fenestration.
The anomaly was identified during the work-up for a foramen magnum mass.
This presentation is unusual as fenestrations are typically extracranial.

Findings:

Intracranial vertebral artery fenestration is a rare finding.
The clinical significance of vertebral artery fenestration remains unclear.
Association with other vascular anomalies has been reported in multiple studies.

Implications:

Awareness of vertebral artery fenestration is crucial for neurosurgeons and interventional radiologists.
Knowledge of this anomaly helps prevent iatrogenic injuries during endovascular interventions.
Further research is needed to understand the clinical significance and management of intracranial vertebral artery fenestrations.
