Trigeminal neuralgia caused by vertebrobasilar dolichoectasia is a rare condition. It is characterized by paroxysmal hemifacial pain which is lancinating in type mostly refractory to medical management. This is a report of trigeminal neuralgia secondary to vertebral dolicholectasia refractory to medical management treated with cyber knife stereotactic radiosurgery to the dose of 66 Gy in single fraction to the proximal nerve root. Pain relief was achieved immediately after the treatment and with a follow up period of 2 years, patient is pain free. Cyberknife assisted radiosurgery is relatively safe in delivering high ablative doses with precise conformality to small target regions like proximal nerve root entry of trigeminal nerve with no major toxicities and achieving early pain relief. It is an outpatient and non-invasive procedure. It can be used as a definite treatment modality for trigeminal neuralgia induced by vertebrobasilar dolichoectasia.
