A 48-Year-Old with Progressive Weakness and Pain

Guillain-Barré syndrome may present in several ways, although predominant proximal weakness is a common feature of the disease to recognize. The differential diagnosis may be extensive and can include infection, vasculitis, toxin exposure, and malignancy. A lumbar puncture must be done with minimal delay to evaluate for cerebrospinal fluid (CSF) albuminocytological dissociation, however results may be normal early in the course of the disease. EMG/NCS are helpful to support the diagnosis, and early treatment with intravenous immunoglobulin (IVIG) is essential. This chapter discusses the clinical features and diagnostic considerations of this important condition.
