title: A rare case of nasal schwannoma with intracranial extension.
abstract: A rare case--only the fourth as known--of a nasal schwannoma with intracranial extension is presented. A 28-year-old Japanese man complained of right nasal obstruction and bleeding for one year. A biopsy indicated the presence of a nasal schwannoma. Computed tomography and magnetic resonance imaging demonstrated intracranial extension of the tumour. The patient underwent surgery with a combined intra- and extracranial approach. Reconstruction was performed using pericranial flaps. Surgical management of this tumour is also described.
