We experienced a case of Ramsay Hunt syndrome accompanied by acute cerebellar ataxia. The patient was a 70-year-old woman who developed left facial palsy with otalgia, typical findings of Ramsay Hunt syndrome. She was treated with an antiviral reagent and steroid under admission; however, she noticed dizziness about 1 week later. Flutter-like oscillations and gaze nystagmus were noted. These neurological signs and symptoms were found to have been caused by varicella-zoster virus infection via an auto-immune mechanism.
