What is considered a normal measurement of the lateral ventricle in the fetal brain?

• A. 5 mm
• B. 7 mm
• C. 10 mm
• D. 13 mm

Answer: (C)

A normal measurement of the lateral ventricle in the fetal brain is typically around 10 mm in diameter during the second and third trimesters of pregnancy. This measurement is crucial in evaluating for conditions such as ventriculomegaly, which is an abnormal enlargement of the lateral ventricles and could indicate potential neurological issues or developmental delays. A measurement less than 10 mm generally suggests normal ventricular size, while anything significantly larger could warrant further investigation. Understanding these measurements helps healthcare providers to monitor fetal development effectively and to make informed decisions regarding maternal and fetal health.
