Guillain-barré syndrome in pregnancy: early diagnosis and treatment is essential for a favorable outcome.

Guillain-Barré syndrome (GBS) is an acute or subacute demyelinating polyneuropathy that rarely complicates pregnancy, but increases maternal and perinatal morbidity. A 15-year-old pregnant woman was admitted with ascending paralysis and acellular lumbar puncture suggestive of GBS. She required mechanical ventilation for 26 days, and was treated with intravenous immunoglobulin and corticosteroids.
