Abstract

CHAMADOIRA, C.; CEREJO, A.; DUARTE, F.  and  VAZ, R.. Trigeminal neuralgia caused by contra lateral cerebellopontine angle tumor: A case report. Neurocirugía [online]. 2010, vol.21, n.1, pp.50-52. ISSN 1130-1473.

In most cases, trigeminal neuralgia is due to compression of the trigeminal nerve in the zone of entrance at the pons by vascular structures. About 1% of cases, have trigeminal neuralgia associated with the presence of ipsilateral lesion of cerebellar-pontine angle. Rarely, trigeminal neuralgia may be due to contralateral posterior fossa tumors. We present a case of a 37-year- old patient who presented with right trigeminal neuralgia and harboured a left acoustic neuroma of significant dimension. Facial pain completely disappeared after tumor removal.

Keywords : Acoustic neuroma; Cerebellopontine angle; Contra lateral pain; Trigeminal neuralgia.
