Summary
Vascular compression of the eighth cranial nerve can cause disabling vertigo. Surgical decompression or selective nerve sectioning can relieve symptoms while preserving hearing.
Area of Science:
- Neurology
- Neurosurgery
- Otolaryngology
Background:
- Vascular compression syndromes affecting cranial nerves in the posterior cranial fossa are increasingly recognized.
- The eighth cranial nerve (vestibulocochlear nerve) may be involved, leading to auditory and vestibular symptoms.
Observation:
- A patient presented with disabling peripheral vertigo unresponsive to medical treatment.
- Magnetic resonance imaging revealed a tortuous basilar artery compressing the eighth cranial nerve.
Findings:
- Surgical exploration confirmed the vascular compression of the eighth nerve.
- A selective section of the vestibular nerve component of the eighth nerve resulted in complete symptom resolution.
- Hearing function was preserved post-operatively.
Implications:
- This case provides clear evidence for eighth nerve vascular compression as a cause of peripheral vertigo.
- It highlights the efficacy of surgical intervention for refractory vestibular symptoms due to neurovascular conflict.
- Further research into the mechanisms and surgical management of eighth nerve compression syndromes is warranted.
