Guillain-Barré syndrome, acute inflammatory demyelinating polyradiculoneuropathy, is acutely or subacutely evolving paralytic disease caused by unestablished etiology. It's antecedent events are upper respiratory infection, unexplained fever, vomiting, diarrhea, vaccination, viral and bacterial infection, and surgical procedure, in order of frequency. Measles infection is known as the rare antecedent event of Guillain-Barré syndrome. The acute axonal form of Guillain-Barré syndrome is characterized by rapid progression to severe widespread paralysis and show respiratory dependence within 2-5 days of the onset of weakness with very poor and delayed recovery. But in this presented case, axonal Guillain-Barré syndrome and combined encephalitis caused by measles infection, 14 year-old girl showed rapid and good recovery though suffered from severe clinical course. This case illustrates prognostic indicator in adult can't apply to child. So more study about causative agents, classification, and prognostic indicator is necessary.
