Cerebellopontine angle tumors are not a frequent cause of trigeminal neuralgia.

The present case shows that a cerebellopontine angle meningioma can cause trigeminal nerve compression with resultant trigeminal neuralgia symptoms. We want to emphasize the importance of investigating each case of trigeminal neuralgia until reaching the correct diagnosis. If the patient has symptoms of trigeminal neuralgia, whether typical or atypical, brain MRI should be considered as the modality of choice.
