Review of the liter-ature revealed only seven reported cases of this tumor. The authors present a child case of jugular foramen meningioma with intra and extracranial extension.

A 9-year-old boy was admitted to the Department of Neurosurgery, Hiroshima University School of Medi-cine on March 20, 1985. Since the age of 3, the patient had hoarseness and was found to tilt his neck when he shouted. Since the age of 6, he was found to nod when he swallowed.
