Nasoethmoid schwannoma with intracranial extension. Case report and review of the literature.

ABSTRACT

Nasoethmoid schwannomas with significant intracranial extension are rare tumours that typically present with visual and olfactory deficits. We describe a nasoethmoid schwannoma in a patient who was completely asymptomatic. Despite impressive intracranial involvement, nasoethmoid schwannomas may present asymptomatically and should be considered in the differential of contrast-enhancing anterior skull base lesions.
