title: Electromyographic studies in a case of foramen magnum meningioma.
abstract: Atrophy of muscles innervated by the lower cervical cord is a well-known feature in patients with foramen magnum tumours. Electromyographic evidence of denervation in the atrophic muscles is presented. The significance and possible mechanisms are reviewed and discussed.
