Abstract

Fetal ventriculomegaly is one of the most common findings on prenatal ultrasound, and one of the most common indications for fetal magnetic resonance imaging (MRI). The aim of this article is to explain the different terminology used to describe the dilatation of the fetal cerebral ventricles, explain the impact of imaging (ultrasound and MRI) in this clinical scenario, illustrate common causes of ventriculomegaly and summarise the evidence regarding prognosis for these children, in order to be able to provide appropriate prenatal advice.

Resumen

La ventriculomegalia fetal es uno de los hallazgos más frecuentes que se encuentran en la ecografía prenatal y una de las indicaciones más comunes de resonancia magnética fetal. El propósito de este artículo es definir la diferente terminología utilizada para describir la dilatación del sistema ventricular cerebral fetal, explicar el impacto de la imagen (ecografía y resonancia magnética fetal) en este escenario clínico, ilustrar con casos las causas más comunes y mostrar la evidencia que existe sobre el pronóstico de estos niños, para proporcionar un consejo prenatal adecuado.
