Abstract The fetal cerebral ventriculomegaly is the most common central nervous system abnormality. Fetuses with ventriculomegaly can be detected at early stage by prenatal ultrasonography. Ultrasound can dynamically monitor the width of fetal lateral ventricle. Magnetic resonance imaging has various clinical value and significance for evaluation the development of the fetal brain. As a necessary complement to ultrasound, MRI is used not only to determine the expansion degree, to find the cause and associated abnormalities, but also to evaluate the prognosis after birth. The prognosis of fetal lateral ventricle enlargement varies considerably. While isolated mild ventriculomegaly has better prognosis in which lateral ventricle width <12 mm. For incompletely back to normal of the lateral ventricle in uterus, fetus should be paid attention to long-term follow-up after birth.
