An acute pharyngeal-cervical-brachial (PCB) variant of Guillain-Barre syndrome presenting with isolated bulbar palsy.
Acute Guillain-Barre syndrome (GBS) is characterized by an acute onset of limb weakness and areflexia. There are a few rare variants that have been described and one of them is the pharyngeal-cervical-brachial (PCB) variant (oropharynx, neck, and proximal upper limb muscles). However, in this patient, the only presentation was bulbar involvement with fast recovery within days. This is likely to be the milder form of PCB that has rarely been described before. A 19-year-old Malay lady presented with progressive dysphagia associated with nasal voice for one week duration. There was no limb weakness. Examination showed generalized areflexia. Pharyngeal and palatal muscles were markedly weak. Cerebrospinal fluid (CSF) examination showed raised protein level. Nerve conduction studies revealed generalized demyelinating motor polyneuropathy consistent with GBS. The patient fully recovered within three days and was discharged well.
