SIQUEIRA, Mario G. et al. Naso-ethmoid schwannoma with intracranial extension: case report. Arq. Neuro-Psiquiatr. [online]. 2001, vol.59, n.2B, pp.421-423. ISSN 1678-4227.

Intranasal schwannomas are rare lesions, specially when they present with an intracranial extension. The fifth case in the medical literature of a naso-ethmoid schwannoma with extension into the anterior cranial fossa is presented. The magnetic resonance findings and the details of the combined intracranial / transfacial operative approach used are described. The possible origin and the clinical characteristics of this rare lesion are reviewed.

Keywords : schwannoma; intranasal schwannoma; paranasal sinus tumor.
