AN ATYPICAL PRESENTATION OF THE PHARYNGOCERVICOBRACHIAL VARIANT OF GUILLAIN-BARRÉ SYNDROME. CASE REPORT.

Abstract

Introduction: Pharyngocervicobrachial syndrome (PCBS) is a clinical variant of Guillain-Barré syndrome (GBS) described by Ropper in 1986. It is a rare presentation with a prevalence of less than 5% worldwide, and is mainly detected in Asia and North America. It is characterized by acute or subacute dysphagia, weakness of the oropharyngeal muscles, neck, and arms, with preserved sensation.

Clinical case: A patient presented with a one-month history of cough, right ear pain, myalgia, and headache, which did not improve with treatment. Subsequently, the patient developed dysphagia, nasal voice, and weakness in head support. Paraclinical results and imaging studies ruled out structural damage. The clinical presentation was considered to be Guillain-Barré syndrome with pharyngeocervicobrachial weakness and facial diplegia. Treatment required immunoglobulin, which resulted in clinical improvement.

Conclusions: The aim is to present the clinical case of a patient with atypical manifestations.
