Contralateral trigeminal neuralgia in a rapidly growing vestibular schwannoma: A case report

We present a rare case of vestibular schwannoma (VS) with contralateral trigeminal neuralgia. A 59 year-old woman presented with right-sided trigeminal neuralgia and a small VS in the left cerebellopontine angle (CPA) that was found via magnetic resonance imaging. The patient was administered medication; however, her symptoms gradually aggravated, and the size of the tumor increased. Two years after the initial diagnosis, the patient underwent surgical resection. After surgical resection, the patient's facial pain was improved. The trigeminal neuralgia appeared to be related to brainstem displacement caused by the contralateral VS. For VS with contralateral trigeminal neuralgia, surgical resection of the tumor should be considered as a possible treatment strategy.
