Persistent hypoglossal artery in association with advanced atherosclerosis

Area of Science:

• Neurology
• Vascular Anatomy
• Medical Imaging

Background:

• The persistent hypoglossal artery is a rare congenital anomaly.
• It arises from the internal carotid artery and supplies the vertebrobasilar system.
• Its clinical significance is often debated and linked to associated pathologies.

Observation:

• A case of persistent hypoglossal artery was identified.
• The anomaly was present alongside atherosclerosis and thrombosis.
• No immediate clinical significance was attributed to the persistent hypoglossal artery in this instance.

Findings:

• The persistent hypoglossal artery, despite coexisting atherosclerosis and thrombosis, did not appear to be clinically significant in this reported case.
• This suggests that the anomaly itself may be asymptomatic or less impactful than previously assumed when other vascular risk factors are present.

Implications:

• This case highlights the variable clinical presentation of the persistent hypoglossal artery.
• Further research is needed to fully understand the risk stratification and management of patients with this anomaly.
• Understanding such variations is crucial for accurate diagnosis and treatment of cerebrovascular diseases.
