Abstract

This clinical study reported a case of trigeminal neuralgia caused by intracranial tumor. A-34-year old female was referred to our clinic with a chief complaint of fulminate pain on the gingiva at the right side of the under jaw. On oral, a carbamazepine, a herb medicine were administrated, and acupuncture was applied and as the result, pain was alleviated. However, two months later, the pain recurred and during the attack of the pain, tinnitus occurred. Intracranial tumor was suspected and CT (Computed Tomography) and MRI (Magnetic Resonance Imaging) disclosed the presence of tumor in the right cerebellopontile angle. The tumor was removed at the Department of Neurocerebral Surgery and was diagnosed histpathologically as an epidermoid. After the operation, the pain disappeared and now after 11/6 postoperative years, she shows favorable prognosis. Since trigeminal neuralgia of unknown cause may sometimes be ascribable to tumor near the trigeminal nerve, like in the present case, it will be necessary to neurocerebral examine as CT and MRI.
