| ABSTRACT |
|
Most intracranial schwannomas originate from the cranial nerve especially CN V, VIII. However, schwannomas from low-cranial nerve are rarely reported. We report a case of large foramen magnum schwannoma in a 26 year-old-man presenting swallowing difficulty, nausea and vomiting.
Magnetic resonance image revealed a cystic multilobulated huge mass from midclivus to atlas which compressed brain stem. The mass was removed by far-lateral transcondylar approach and confirmed with schwannoma which originated from hypoglossal nerve. |
