Chronic inflammatory demyelinating polyneuropathy (CIDP) is a chronic recurrent acquired immune-mediated disease of the peripheral nerves that presents with progressive sensory and motor deficits in all four limbs. Cranial nerve involvement is not as common as in Guillain-Barre syndrome, and central nervous system involvement including optic neuritis has rarely been reported in patients with CIDP. We recently experienced a case with classic CIDP involving bilateral facial and trigeminal nerves, right lower cranial nerves, and the right optic nerve.

Guillain-Barr? syndrome is a disorder of acute polyneuropathy that is described as progressive, symmetric muscle weakness. Many reports have documented the occurrence of Guillain-Barr? syndrome after vaccination. Here, we report a very rare case of patient with Guillain-Barr? syndrome who presents with unilateral foot drop after receiving tatanus toxoid injection. Four days after the symptom onset, limbs weakness developed, and the patient showed delayed right peripheral facial palsy.
