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.
