Self-limited acute encephalopathy related to measles component of viral triple vaccine
Summary. Introduction. Neurological disorders secondary to the measles component of viral triple vaccine are not frequent. In spite of controversy regarding the cause, the clinical, diagnostic and legal implications are worth considering. Clinical case. We present the case of a 16 monthold baby with a clinical picture of self-limiting acute encephalopathy characterized by cerebellar ataxia and alterations in behavior, accompanied by the clinical signs of attenuated measles. The negative results of complementary tests and an obvious time-relationship with a triple virus vaccination lead us to interpret the condition as being secondary to the measles component of the vaccine. Conclusions. We consider that although there is a low incidence of complications, the index of suspicion is also low, and even lower in cases with only minor neurological signs. It is therefore possible that such reactions are under-reported
Caso clínico Presentamos el caso de un lactante de 16 meses con un cuadro de encefalopatía aguda autolimitada caracterizado por ataxia cerebelosa y alteración del comportamiento, acompañado de signos clínicos de sarampión atenuado. La negatividad de las exploraciones complementarias y su clara relación temporal con la vacunación triple vírica nos llevaron a interpretar el cuadro como secundario al componente antisarampionoso de la vacunación.
Conclusiones Creemos que, aunque la incidencia de estas complicaciones es baja, también lo es su índice de sospecha, más aún en los casos con clínica neurológica menor, por lo que es posible que dichas reacciones estén infracomunicadas
