Unilateral peripheral facial nerve palsy is a common, relatively benign, and usually idiopathic condition. Unlike the unilateral form, simultaneous bilateral facial paralysis is a rare clinical entity that often indicates a serious underlying systemic disease that warrants urgent investigation and treatment. We reported a case of a 34-year-old healthy man developing paresthesia in both feet and hands after acute upper respiratory tract infection. Afterwards, he went to an emergency department for severe headache and neck pain, followed by quadriparesis, areflexia, autonomic dysfunction, bulbar weakness, and bilateral facial paralysis. Acute inflammatory demyelinating polyradiculoneuropathy (AIDP) was later diagnosed by cerebrospinal fluid analysis and electrophysiological examination. The literature on Guillain-Barré syndrome was reviewed herein to facilitate prompt recognition and timely referral of this potentially life-threatening disease.
