ResumoHemifacial spasm (HFS) is a movement disorder characterized by involuntary paroxysmal chronic contractions of the facial musculature. The usual cause is vascular compression of the seventh cranial nerve, at its exit zone from the brain stem. We report a case of left hemifacial spasm, in a 66-year-old woman, in which the neuroradiological investigation with magnetic resonance imaging showed a hypervascular soft tissue mass arising from the left skull base, in the jugular foramen. This lesion was thought highly likely to be a glomus jugulare tumour. While the usual occurrence of tumour compression causing HFS has been previously recognized, the association of glomus jugulare tumours presenting with HFS has not. The importance of this association is discussed. Copyright 1999 Harcourt Publishers Ltd.
