Abstract

Trigeminal neuralgia (TN) is the most commonly seen craniofacial pain syndrome. Etiology of TN can be divided into classical (idiopathic and vascular compression) and symptomatic (tumor, demyelinating, and ischemic) types. Especially, symptomatic trigeminal neuralgia is seen with tumors located in the cerebellopontine angle. Epidermoid tumors comprise about 1% of all brain tumors and 5% of tumors located in the cerebellopontine angle. These tumors may present with trigeminal neuralgia due to localization. In this article, we present case with trigeminal neuralgia due to pontocerebellar angle epidermoid tumor, as well as

examine to approach for symptomatic trigeminal neuralgia, due to epidermoid tumors.
