Resumen

El espasmo hemifacial (EH) constituye una entidad clínica caracterizada por contracciones tónico-clónicas de carácter involuntario de la musculatura inervada por el nervio facial. Como forma de presentación de meningiomas intracraneales es excepcional. Presentamos tres casos de pacientes con meningiomas cuya presentación clínica fue en forma de EH, bien de forma aislada o asociado a sintomatología de hipertensión intracraneal o déficit neurológico focal. Se revisa la literatura y se discuten los posibles mecanismos fisiopatológicos que puedan intervenir en esta asociación.

Summary

Hemifacial spasm (HFS) is a clinical entity consisting of brief clonic jerking movements of the facial muscula-ture, 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 excepcional 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 déficit. We review the literature and discuss the possible physiopathological mechanisms responsible for this association.
