Guillain-Barré syndrome (GBS) encompasses a variety of clinical manifestations, including the rare and easily underdiagnosed pharyngeal-cervical-brachial variant (PCB). Here, we present the case of a 57-year-old woman with no significant medical history who lives in an area endemic for vector-borne diseases. She presented to the emergency department with four days of cervicobrachial weakness and acute dysphagia. Although imaging was normal, lumbar puncture revealed albuminocytologic dissociation and neurophysiological tests demonstrated acute demyelinating polyradiculopathy, confirming the diagnosis of the CPB variant. First described in 1986, this variant has been reported following arbovirus infections, such as dengue and chikungunya. This case highlights the importance of considering this atypical form of GBS and suggests the need for future research on its possible association with vector -borne infection.

In the last five years, there have been several cases of zika and chikungunya infections in the world, simultaneous with the increase in cases of Guillain-Barre syndrome, which have shown a potential causal relationship that is still not entirely clear. Objective: To describe the main clinical manifestations of Guillain-Barre syndrome in relation to chikungunya and zika, according to scientific literature. Methods: The databases PubMed and ScienceDirect were used to perform the search for the period 2014-2016 using with the keywords: zika, chikungunya and Guillain-Barre Syndrome; articles in English and Spanish were included. Results: 35 articles were found, one for the year 2014, two for 2015 and 32 for 2016. Conclusion: Variations in clinical characteristics and the increased incidence of GBS in the presence of zika and chikungunya, highlight the need to monitor these infections and perform analytic studies to determine the association between arboviruses and different neurological alterations.
