Trigeminal neuralgia secondary to tumor with normal exam, responsive to carbamazepine.
Trigeminal neuralgia is most commonly idiopathic, although it can be associated with multiple sclerosis. Tumors are rare causes of trigeminal neuralgia. A case is presented of trigeminal neuralgia with normal neurological examination and responsive to carbamazepine, secondary to a cerebellopontine angle meningioma. Literature relative to neoplastic etiologies of trigeminal neuralgia is reviewed. The role of electrodiagnostic testing in the evaluation of trigeminal neuralgia is considered. A normal neurological examination and responsiveness to carbamazepine do not exclude tumor as an etiology of trigeminal neuralgia.
