Miller-Fisher syndrome and Bickerstaff brainstem encephalitis, among others, constitute the anti-GQ1b syndrome, with a common immune pathophysiologic pathway characterized by the presence of anti-GQ1b antibodies, which react against the different nervous system GQ1b sites according to their different accessibility. The Miller-Fisher syndrome has a prevalence of 0.09 cases per 100 000 people-year but there are not epidemiological studies about Bickerstaff brainstem encephalitis, that it seems to be less frequent. In spite of having a good natural outcome, the immunoglobulin administration has been established as efficacious at improving it. A twelveyear- old boy suffering from Miller-Fisher-Bickerstaff syndrome after an acute Campylobacter jejuni diarrhea with positive titers of anti-GQ1b and anti-QGT1a antibodies is presented. We communicate a very uncommon pediatric disease with the aim of warning about the importance of its early suspicion and the need of specific laboratory determinations.
