Trigeminal neuralgia secondary to cerebellopontine angle meningioma

Trigeminal neuralgia may be an initial presenting symptom indicating a cerebellopontine angle tumors. The pathophysiology of trigeminal neuralgia is not clearly understood, the compression of nerve root due to the blood vessel or tumor around trigeminal nerve is considered to be a major cause. Local pressure causes demyelination that leads to abnormal depolarization resulting in ectopic impulses.

If the patient has a symptom of atypical trigeminal neuralgia brain MRI should be considered.
