title: A rare case of olfactory neuroblastoma with intracranial extension.
abstract: Olfactory neuroblastoma (ONB) is a rare form of head and neck tumor, and further ONB presenting an intracranial extension is extremely rare. Therefore, at the present time there is no established therapeutic standard supported by oncological studies. Our report documents a patient who underwent a craniotomy in combination with transnasal approach for tumor excision, followed by postoperative irradiation. We conclude that the patient shows no evidence of recurrence during the 11-year follow-up involving sinus CT scans and endoscopic examinations.
