[Guillain-Barré syndrome with central nervous system symptoms. Report of two cases]

Guillain-Barré syndrome - acute inflammatory demyelinating polyradiculoneuropathy - is characterized by symmetrical flaccid paresis of limbs and areflexia or hyporeflexia which progress over a few days, up to 4 weeks. The central nervous system lesion is rarely reported in the course or treatment of the disease. In the paper two cases of patients with diagnosed Guillain-Barré syndrome with the central nervous system manifestations were discussed. A case of a 55-year-old woman was presented, who during hospitalization, on the last day of intravenous immunoglobulin therapy developed a hallucinatory syndrome. Furthermore, a case of a 18-year-old female patient with classic features of Guillain-Barré syndrome was described, because of its atypical initial presentation (headache, drowsiness and meningismus).
