Summary
This study details the first reported case of an arteriovenous malformation (AVM) originating within the trigeminal nerve. The AVM was successfully removed, offering new insights into rare neurological conditions.
Area of Science:
- Neurosurgery
- Neurology
- Vascular Neurology
Background:
- Arteriovenous malformations (AVMs) are abnormal tangles of blood vessels.
- Trigeminal nerve involvement by AVMs is rare, with previous cases involving adjacent structures.
- Sudden onset headache and ataxia can indicate serious neurological events.
Observation:
- A 76-year-old man presented with acute headache and ataxia.
- Imaging revealed an arteriovenous malformation within the trigeminal nerve.
- Surgical resection was performed via a lateral suboccipital approach.
Findings:
- The arteriovenous malformation was confirmed angiographically, surgically, and pathologically.
- This represents the first documented instance of an AVM arising intrinsically from the trigeminal nerve.
- Complete resection of the AVM was achieved.
Implications:
- This case expands the known spectrum of AVM locations.
- Understanding trigeminal nerve AVMs can improve diagnostic and treatment strategies.
- Highlights the importance of considering rare pathologies in neurological presentations.
