Ventriculomegaly

This is my first pregnancy, baby's head has measures large the entire pregnancy. I went for a growth scan today at 33 weeks and was told that baby boys left brain ventricle is dilated to 13.4 MM which is mild Ventriculomegaly and the right ventricle is dilated to 11.9 MM. everything else looks normal and has the entire pregnancy but as you can imagine it's very scary news to get. I was wondering if this has happened to anybody else and what the results were. Thanks in advance:)
