Persistent hypoglossal artery aneurysm: Case report and qualitative systematic review

Area of Science:

• Neuroscience
• Vascular Surgery
• Medical Imaging

Background:

• Persistent hypoglossal artery is a common developmental anomaly.
• Intracranial aneurysms require prompt treatment, with endovascular coiling being a standard approach.
• Data on treating aneurysms associated with persistent hypoglossal arteries is scarce due to low incidence.

Observation:

• A case report of the oldest patient treated for a persistent hypoglossal artery-associated aneurysm.
• The aneurysm originated at the posterior inferior cerebellar artery.
• Endovascular treatment was successfully performed via the persistent hypoglossal artery.

Findings:

• This case represents the first reported endovascular treatment of a persistent hypoglossal artery aneurysm.
• Endovascular therapy is a safe and effective treatment option for ruptured posterior inferior cerebellar artery aneurysms arising from a persistent hypoglossal artery.
• A qualitative review of literature indicates a predominance of surgical interventions for similar cases.

Implications:

• Endovascular treatment should be considered for persistent hypoglossal artery aneurysms, particularly when arising from the posterior inferior cerebellar artery.
• This case expands treatment options for rare cerebrovascular pathologies.
• Further case studies and literature reviews are needed to solidify evidence for endovascular approaches.
