A Case of Pharyngeal-Cervical-Brachial Variant of Guillain-Barré Syndrome With Bilateral Glossopharyngeal Paralysis.

Guillain-Barré Syndrome (GBS) is a rapidly evolving autoimmune inflammatory disease of the peripheral nerves. It classically presents with progressive symmetrical ascending muscle weakness and hyporeflexia. The pharyngeal-cervical-brachial (PCB) variant is a rare variant of GBS that is characterized by axonal rather than demyelinating neuropathy and presents with rapidly progressive oropharyngeal (facial palsy, dysarthria) and cervicobrachial weakness, associated upper limb weakness, and hyporeflexia.
