title: An arachnoid cyst involving only the hypoglossal nerve: case report and review of the literature.
abstract: We describe a patient with an arachnoid cyst, possibly of traumatic origin, at the hypoglossal canal producing atrophy of the tongue. An arachnoid cyst should be considered in the differential diagnosis of any patient with a localized cystic mass around the cranial nerves at the base of the skull.
