Summary
A rare persistent hypoglossal artery with arteriovenous malformation was diagnosed using MRA. This condition led to intracranial hemorrhage during pregnancy, highlighting the need for advanced imaging.
Area of Science:
- Neurology
- Radiology
- Vascular Surgery
Background:
- Persistent hypoglossal artery is a rare congenital vascular anomaly.
- Arteriovenous malformations (AVMs) are complex vascular lesions.
- The co-occurrence of these two conditions is exceptionally rare.
Observation:
- A pregnant patient presented with intracranial hemorrhage.
- Magnetic Resonance Angiography (MRA) clearly visualized the persistent hypoglossal artery and AVM.
- Advanced imaging including MRI, angiography, and CT were utilized.
Findings:
- The study reports a unique case of persistent hypoglossal artery associated with an intracranial arteriovenous malformation.
- MRA proved highly effective in delineating the intricate vascular anatomy.
- The patient experienced a critical event of intracranial hemorrhage during late-term pregnancy.
Implications:
- This case underscores the diagnostic utility of MRA in identifying rare cerebrovascular anomalies.
- Understanding such rare vascular variants is crucial for managing intracranial hemorrhage in pregnancy.
- Further research into the management of co-existing persistent hypoglossal artery and AVM is warranted.
