Summary
A rare basilar artery duplication, a variation from unfused posterior neural arteries, was incidentally found in a hypertensive patient with visual disturbance. This finding highlights a less common vascular anomaly potentially affecting cerebral blood flow.
Area of Science:
- Vascular anatomy
- Neurology
- Medical imaging
Background:
- Basilar artery duplication is a rare congenital vascular variation.
- It arises from the incomplete fusion of posterior longitudinal neural arteries.
- Understanding such variations is crucial for interpreting neuroimaging findings.
Observation:
- A 71-year-old male patient with hypertension presented with visual disturbances.
- Magnetic resonance imaging (MRI) incidentally revealed a duplicated basilar artery.
- The duplicated artery ran parallel to the main basilar artery, originating from the vertebral artery and extending to the anterior inferior cerebellar artery.
Findings:
- The study reports a case of basilar artery duplication, a rare vascular anomaly.
- This condition results from the non-fusion of posterior longitudinal neural arteries.
- The duplicated vessel was visualized alongside the main basilar artery on MRI.
Implications:
- Basilar artery duplication, though rare, is a significant finding in vascular neurology.
- Accurate identification is essential for differentiating from other pathologies and understanding potential hemodynamic effects.
- Further research into the clinical significance and prevalence of basilar artery duplication is warranted.

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
