title: Trigeminal neuralgia secondary to tumor with normal exam, responsive to carbamazepine.
abstract: 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.
