Epidermoid Cyst of the Cerebellopontine Angle Presenting with Contralateral Trigeminal Neuralgia: Extremely Rare Case and Review of Literature.

Abstract

An epidermoid cyst is a rare tumor of the cerebellopontine angle region. It usually presents with ipsilateral compressive symptoms. The contralateral trigeminal neuralgia is an unusual presentation in such cases. We did not find such case reports in the literature. Here, we report a case of a 62-year-old female with a right cerebellopontine angle epidermoid cyst presenting with right hearing impairment and the contralateral trigeminal neuralgia. The possible mechanism leading to the contralateral trigeminal neuralgia is discussed here along with the diagnosis and management of the case.
