This report presents a case of 61-year-old male patient who recourse to the emergency department with facial pain and asymmetry followed by peripheral unilateral facial nerve paralysis that there was no obvious cause. The patient eventually was discharged from hospital with an outpatient therapy of corticosteroid for 3 weeks, the regular courses of physical rehabilitation for the facial muscles weakness and recommendation to return for follow up in the future. Finally, after 4 months of treatment, the patient's facial weakness disappeared thoroughly without complication.
