The second most frequent location for meningiomas of the posterior fossa is on the anterior rim of the foramen magnum. These tumors may extend for a considerable distance up the clivus or down into the spinal canal. These slow-growing tumors may cause remarkable distortion and compression of the cervicomedullary region. The vertebral artery and its branches, as well as the lower cranial nerves, may be completely enveloped by the tumor (Fig. 32-1).
