- Abstract
- Intracranial schwannomas are relatively common benign tumors arising from Schwann cells. Among the cranial nerves, the vestibular division of the vestibulocochlear nerve is the site most commonly affected by these lesions, followed by the trigeminal nerve. The authors report a case of bilateral schwannomas arising from both of the pterygoid canals. A 13-year-old girl presented with intermittent headaches and left-sided facial palsy. Preoperative computerized tomography scans and magnetic resonance images revealed nonenhancing round masses within the bilateral vidian canals, bone erosion, and sclerosis. The transnasal transseptal transsphenoidal approach was used to remove the masses. Postoperatively, the patient recovered uneventfully. On histopathological examination, the masses were confirmed as schwannomas. The clinical presentation and probable histogenesis of schwannomas arising in this location are discussed together with a review of the literature.
