Objective:

To evaluate the value of the lateral ventricle and cerebellum plane scanning in the diagnosis of fetal central nerve system (CNS) midline structure abnormalities.

Methods:

Ultrasound imaging features of 97 fetuses with fetal CNS midline structure abnormalities from 3 921 abnormal fetuses were analyzed retrospectively.

Results:

Among the 97 fetuses

there were 9 cases of encephalocele

7 cases of anencephaly

4 cases of meningocele

11 cases of transparent septum widened

16 cases of complete agenesis of the corpus callosum (ACC)

15 cases of partial ACC

15 cases of holoprosencephaly

4 cases of arachnoid cyst

10 cases of Dandy-Walker malformation

4 cases of malformation Arnold-Chiari ty

pe Ⅱ

and 2 cases of vein of Galen aneurysm malformation.

Conclusion:

The lateral ventricle and cerebellum plane scanning is a safe

liable

practical and quick method to diagnose the fetal CNS midline structure abnormalities.
