baby's left lateral ventricle


I am 20 weeks pregnant.  All first and second trimester screenings/bloodwork have been normal.  At my 20 week ultrasound, my OB was concerned because the baby's left lateral ventricle was at the top end of the normal range (measuring 10 mm).  The technician measured once (measuring 10mm) and the doctor came in and measure twice. (Once measuring 9mm and the second measuring 8mm). She explained this would be considered "Mild Ventriculomegaly" and advised I return in 4 weeks for another scan. Should this cause concern, and do you think there is anything else I should be asking? I should also mention Baby was in the BREECH position during the entire scan.  I would greatly appreciate it.  Thanks!

Hi there.  Congrats on being half way through your pregnancy!  I am sure this is worrisome to you!  You are seeming to be to me 'just under' where mild ventriculomegaly begins which is at 10 to 15 mm. I'm going to post a link and here is a helpful quote to keep in mind from the link.  "Mild ventriculomegaly is different from the more severe form of ventriculomegaly, hydrocephalus or “water on the brain”.  About 1 in every 500 babies will have mild ventriculomegaly. In most cases, babies with this ultrasound finding are born healthy."  So this is common and often does not have a negative consequence for baby.  https://mydoctor.kaiserpermanente.org/ncal/Images/GEN_US%20Ventriculomegaly%20handout%206-09_tcm63-18471.pdf

They will likely follow you a little more closely but right now, I would ask how they will be monitoring you.  What prenatal testing you should have. What the risks are.

Please stay in touch so I can know how this goes. I'm sending you big hugs
