Article Figures & Data
Figures
- Fig 1.
Distribution of ventriculomegaly cases according to severity and the presence or absence of asymmetry. Filled bars represent asymmetric ventriculomegaly; empty bars represent symmetric ventriculomegaly.
- Fig 2.
Distribution of additional CNS findings in cases of fetal ventriculomegaly according to maximal ventricle width. Filled bars represent major CNS findings, dotted bars represent minor CNS findings, and empty bars represent no additional CNS findings. Due to small numbers, cases with dilation of ≥16 mm were grouped together.

Distribution of additional CNS findings in cases of fetal ventriculomegaly according to ventriculomegaly severity and the presence or absence of asymmetry. Filled bars represent major CNS findings, dotted bars represent minor CNS findings, and empty bars represent no additional CNS findings.
