Abstract

|
The bibrachial variant of Guillain-Barre syndrome (GBS) is characterized by rapidly progressive and predominant weakness of both upper extremities with hyporeflexia or areflexia. Because the bibracial variant is rare, the pathomechanism and disease course has not been clarified. We report a 42-year-old man with rapidly progressive weakness of both arms. His electrophysiological study showed partial conduction blocks of motor nerves normalized without development of excessive temporal dispersion within 3 weeks. This case suggests that the main pathophysiological mechanism is reversible conduction block and it may be in the continuous spectrum of axonal motor GBS subtype.
