Abstract
We describe all cases of nasoethmoid schwannomas with intracranial extension reported in the literature, including an original case report describing the successful gross total resection of a nasoethmoid schwannoma with intracranial extension. Ten cases of nasoethmoid schwannoma with intracranial extension have previously been reported. These lesions most often appear in the second through fourth decades of life and commonly present with anosmia, headache, and visual deficits. Bifrontal craniotomy was the predominantly implemented surgical approach and gross total resection was achieved in all cases, except for one. In conclusion, nasoethmoid schwannoma with intracranial extension is a rare disease entity that is most often benign and is most commonly treated by gross total resection using a bifrontal craniotomy approach.
