Guillain-Barr syndrome presenting progression from unilateral to bilateral facial palsy

일측에서 양측으로 진행한 안면마비를 주소로 내원한 길랑-바레 증후군

Otolaryngologists are often faced with patients who have unilateral facial palsy. However, bilateral facial palsy without any other neurologic and systemic symptom is very uncommon that we should keep in mind the possibility of other diseases which cause it, including bilateral bell’s palsy, Lyme disease, Guillain-Barr syndrome (GBS), Leukemia, Sarcoidosis, Infectious mononucleosis and trauma. We describe a 39-year-old male patient who had unilateral facial palsy at first, and progressed to bilateral facial palsy a few days later. His clinical course and neurophysiologic studies, cerebrospinal fluid study are consistent with GBS. We review this case with relevant publishes in medical literature.
