Severe fetal ventriculomegaly is generally associated with poor prognosis in terms of survival and neurodevelopment outcome. As such, many parents opt to terminate the pregnancy independently of a known etiology. We report here the case of a female fetus with severe progressive ventriculomegaly due to the unexpected presence of bilateral nodular periventricular heterotopias visualized on MRI of a fetal brain. Reaching a structural diagnosis was perceived as a relief for the parents and the pregnancy was continued. Neurodevelopment assessment at 3 years of age is normal with no epilepsy.
