Sudden deafness and cerebellar tumour.

We report the case of a female patient who presented with sudden deafness as the first symptom of a cerebellar tumour which was not localized strictly in the cerebellopontine angle and did not show direct compression on the extrabulbar portion of the VIIIth cranial nerve. The clinical picture contained a number of signs and symptoms typical of cerebellar involvement. Surgical intervention restored the hearing and caused the symptoms to disappear. We also review the association between tumours and sudden deafness in the literature.
