title: [Hemifacial spasm as clinical presentation of intracranial meningiomas. Report of three cases and review of the literature].
abstract: Hemifacial spasm (HFS) is a clinical entity consisting of brief clonic jerking movements of the facial musculature, beginning in the orbicularis oculi with downward spreading to other facial muscles. Apart from vascular loop compression at the root exit zone of the facial nerve, other causes of HFS are rare. It is exceptional as a form of presentation of intracranial meningiomas We report three cases of patients with meningiomas who presented with HFS, either as an isolated sign or associated with symptoms of rise intracranial pressure or focal deficit. We review the literature and discuss the possible physiopathological mechanisms responsible for this association.
