[Hemifacial spasm disclosing neurinoma of the hypoglossal nerve]. / Spasme hémifacial révélateur d'un neurinome du nerf hypoglosse.

A hemifacial spasm was symptomatic of a neurinoma of the hypoglossal nerve in a 50 year-old woman. It disappeared after the surgical cure of the tumor. Hemifacial spasm is not mentioned among the 19 cases of neurinoma of the hypoglossal nerve which have been reported up to now. The spasm could have been due to the compression of the 7th nerve by the anterior inferior cerebellar artery, displaced by the tumor.
