We report two cases of pharyngeal-cervical-brachial (PCB) variant of Guillain-Barré syndrome (GBS). The patients developed dysphagia and weakness of the neck and arms subsequent to Campylobacter jejuni infection. Oropharyngeal palsy recovered poorly. Electrophysiological findings demonstrated axonal conduction failure. Anti-GD1a immunoglobulin G (IgG) antibody was detected in one case, and anti-GM1b IgG antibody in another. Anti-GT1a IgG and immunoglobulin M (IgM) antibodies were negative in both cases. The current cases suggest that the PCB and axonal variants of GBS form a continuous spectrum from the viewpoint of electrophysiological studies as well as antiganglioside serology.
