Nasoethmoidal schwannomas are rare lesions and their presentation with intracranial extension is even rarer. Here, a patient presenting with rhinorrhea, epistaxis, and proptosis of left eye was diagnosed with giant nasoethmoidal schwannoma extending to frontal lobe and orbit, which was managed with bifrontal craniotomy with endoscopic transnasal gross total excision. This being predominantly a benign lesion has good prognosis if total excision is achieved. [ABSTRACT FROM AUTHOR]
