Nasoethmoidal schwannoma is a benign neoplasm that infrequently exhibits intracranial extension. To date, there have been 17 documented cases in the literature, and this report presents the 18th reported case overall and 6th bilateral case. Because radiographic results are ambiguous, a histological investigation is required for a precise diagnosis. Bifrontal craniotomy combined with endoscopic transnasal excision is the preferred surgical treatment for tumors that extend into the anterior cranial fossa. Long-term clinical follow-up is critical for detecting future recurrences.
