ABSTRACT
Classical trigeminal neuralgia is characterized by recurrent attacks of lancinating pain in the trigeminal nerve distribution, and no cause of the symptoms can be identified, other than vascular compression. This type of injury may rarely be caused by identifiable conditions, including tumor in the cerebellopontine angle. If the patient is suspected for secondary trigeminal neuralgia, further evaluation is required to diagnose and treat correctly. We report a case of a 49-year-old woman with a 1-month history of facial pain, who was initially misdiagnosed as odontalgia, and even treated with the extraction of her molar teeth. This case with the review of secondary trigeminal neuralgia may highlight the difficulties of diagnosis, and the importance of early diagnostic imaging, when trigeminal neuralgia occurs with a brain tumor.
