抄録

We report two cases of symptomatic trigeminal neuralgia with intracranial tumor noticed by tooth extraction, which were diagnosed immediately by MRI. Case 1 was a 21-year-old male who had right facial sharp pain after removal of a right wisdom tooth in the mandible. He was suspected to be suffering from symptomatic trigeminal neuralgia because of his young age, no trigger zone, and pain while asleep. MRI revealed that an epidermoid tumor was compressing the right trigeminal nerve at the root entry zone. Near total excision of the tumor was performed and the pain disappeared. Case 2 was an 85-year-old female who had undergone extraction of stumps of right premolar and molar teeth in the mandible because of a throbbing intermittent pain in the right mandible. She was referred to our hospital because the pain was not relieved even though the wound was cured. The pain nearly disappeared by the administration of Neurotropin<sup>®</sup>. However, she was suspected to be suffering from symptomatic trigeminal neuralgia because of the long duration of pain, no trigger zone, and severe right hypoacusis. MRI revealed that an acoustic nerve tumor was compressing the right trigeminal nerve at the root entry zone. She was not operated on because of her age and the hypoacusis was considered to be irreversible, and so the pain was controlled. It is not always easy to distinguish between typical and symptomatic trigeminal neuralgia by means of only clinical findings. Therefore, it is useful to ascertain the presence of an intracranial process by MRI in order to make an accurate diagnosis of patients with trigeminal neuralgia or atypical facial pain.
