Abstract

Fetal fourth ventricle was prospectively evaluated in 256 fetuses at the first trimester ultrasound screening at 11—14 weeks of gestation. The mid-sagittal view of the fetal face can be used. In this plane the fourth ventricle presents as an intracranial translucency between the brain stem and choroid plexus. In the first trimester the fourth ventricle is visible in 100% cases. The anteroposterior diameter of fourth ventricle was measured in each case. The fourth ventricle at first trimester ranged from 1,62 to 2,34 mm. the normal range of fetal fourth ventricle can be used for early detection of open spina bifida.
