Is it abnormal to have a lateral ventricle width of 9mm?

One ventricular width is often caused by congenital ventricular malformation or by lateral ventricular cyst. If the fetal ventricular width is enlarged, how many centimeters should be observed? Under normal circumstances, ventricular width is less than one centimeter, which is a normal phenomenon, and can be continued to be observed. If the ventricular width is 1 to 1.5 centimeters, this is a mild widening, and it needs to be reviewed. More than 1.5 cm is severe ventricular widening, which requires further prenatal diagnosis. If the lateral ventricle (widening) is 9 mm, it is still in the normal range at this stage, and the patient is recommended to continue observation.
