Summary
A rare cavernous malformation affecting the trigeminal nerve was surgically removed. This case highlights a unique origin from the trigeminal nerve, previously unreported in medical literature for such vascular lesions.
Area of Science:
- Neurosurgery
- Vascular Neurology
- Cranial Nerve Surgery
Background:
- Cavernous malformations (CMs) are rare vascular anomalies.
- Cranial nerve involvement by CMs is exceptionally uncommon.
- Previous reports of CMs in cranial nerves have not specified origin from the trigeminal nerve.
Observation:
- A 54-year-old male presented with a cavernous malformation.
- The malformation involved the Gasserian ganglion and the 2nd and 3rd divisions of the left trigeminal nerve.
- Surgical resection was performed via an extradural approach.
Findings:
- Successful resection of the cavernous malformation.
- Demonstration of a cavernous malformation originating specifically from the trigeminal nerve.
- This represents the first reported case of a trigeminal nerve-originating cavernous malformation.
Implications:
- Expands the understanding of rare cranial nerve pathologies.
- Provides a surgical case study for extradural resection of trigeminal nerve cavernous malformations.
- May guide future diagnostic and treatment strategies for similar rare neurovascular conditions.
