Mild Fetal Ventriculomegaly
Ashish Jain, Karamalla Saddam Hussain
Case Scenario
A 27-year-old primigravida underwent a level 2 antenatal ultrasonography (USG) at 20 weeks of gestation. The USG revealed the presence of an isolated mild ventriculomegaly. No other fetal anomaly was identified on detailed evaluation.
Conclusion
When ventriculomegaly is identified, a thorough evaluation including detailed sonographic examination for fetal anatomy, amniocentesis for the assessment of chromosomal abnormalities, and a workup for fetal infection should be performed. fMRI may identify other abnormalities and can be considered when such results of sonographic imaging and expert interpretation are available. Follow-up USG examination should be performed to assess the progression of the ventricular dilation. In the setting of isolated mild ventriculomegaly (10–12 mm), the likelihood of survival with normal neurodevelopment is > 90%.
