title: Toothache caused by trigeminal neuralgia of vestibular schwannoma: a case report. [Corrected].
abstract: BACKGROUND
  Vestibular schwannoma, also called acoustic neuroma, is a tumor composed of Schwann cells that most commonly involves the vestibular division of the 8th cranial nerve. A thorough medical and dental history and properly conducted diagnostic testing and radiographic evaluation are essential in differentiating odontogenic tooth pain from tooth pain of a nonodontogenic origin.
  
  
  METHODS
  This report discusses a case of acoustic neuroma mimicking odontogenic pain. A 61-year-old man presented with pain in the lower left quadrant. Medical history revealed peripheral neuropathy and prior exposure to Agent Orange. Diagnostic testing on teeth #19, #20, and #21 ruled out an odontogenic cause for the pain. Brushing of a specific region of the face elicited pain that resembled the patient's chief concern. The patient was referred to a craniofacial pain center with the tentative diagnosis of trigeminal neuralgia. Treatment for trigeminal neuralgia was not successful, prompting referral to the neurosurgery department where magnetic resonance imaging was performed.
  
  
  RESULTS
  Magnetic resonance imaging revealed a moderate-size, lobular, left cerebellopontine angle mass lesion consistent with acoustic neuroma with compression of the left trigeminal nerve secondary to the lesion.
  
  
  CONCLUSIONS
  Acoustic neuroma can cause tooth pain secondary to compression of the trigeminal nerve.
