RESUMEN
El síndrome opsoclonus-myoclonus es un trastorno neurológico raro. En la infancia su etiología es variable, aunque en un 40-80% de los casos se trata de una manifestación paraneoplásica, principalmente del neuroblastoma. Con un algoritmo diagnóstico controvertido en la búsqueda de un posible tumor primario, la resonancia magnética de cuerpo entero se vislumbra como una poderosa herramienta. Presentamos el caso de un varón de 2 años con manifestaciones de un síndrome opsoclonus-myoclonus al que se detectó un neuroblastoma retroperitoneal mediante esta técnica de imagen (AU)

Whole-body MRI promises to be a powerful tool in the search for a possible primary tumor in this condition for which the diagnostic algorithm is yet to be established. We present the case of a two-year-old boy with signs of opsoclonus-myoclonus syndrome in whom a retroperitoneal neuroblastoma was detected by whole-body MRI (AU)
