Intracranial schwannoma of the hypoglossal nerve
R. R. Tuck, B. Mokri and J. M. Cilluffo
Two patients had a solitary intracranial schwannoma of the hypoglossal
nerve. Such schwannomas are rare, and these two cases bring the total
number of reported cases to 16. Hemiatrophy of the tongue is always present
but is rarely reported by patients. Diagnosis can be facilitated by
high-resolution computed tomographic scanning of the posterior fossa and
foramen magnum region. The hazards formerly associated with removal of
these tumors have largely been eliminated.
