Thank you SO much girls for your fantastic reassuring responses. I can't thank you enough.

I can relate to those feelings of dread etc you describe when first told of this diagnosis. Just as I had been thinking how very lucky I am to have a cruisy pregnancy, my 20 week scan suddenly flags concern; I am called back in for another scan two days later which resulted in lots of tears and then given an immediate appointment with my ob. I felt quite horrified when termination was discussed. The days since then have felt like a blur.
I love my ob and she is very clear and attentive and wonderful, but unfortunately I am a natural worrier (luckily hubby is always calm, reassuring and rarely freaks out at anything).
Hubby and I were offered amnio and MRI scans; apparently the amnio is only really for consideration if you choose to consider termination, and that there are only a couple of weeks left to organise a termination before ethics committee approval would be required. Anyway, hubby and I are resolute and of the same thinking (thankfully!) that termination is not going to be considered as an option. As mentioned, we too have bonded with this little person who is making her presence known with lots of kicks, and is measuring completely normal in every other way apart from the ventriculomegaly. My 4yo and 2yo are getting concerned and of course they too have bonded in anticipation with their new baby sister.

One thing that absolutely scares me is the looming chance (albeit a small chance) that should things get worse re the ventriculomegaly, I could be admitted as a high risk patient in one of the big hospitals where they would do various invasive procedures to assist the baby before birth and then after birth the shunts etc.

Statistically it seems there is a 93% chance of a great outcome (33% chance the dilated fluid patch would shrink and 60% chance it would stabilise), while there is a 7% chance of a poor outcome. So we are really just hoping for the best! Unfortunately this has cast a dark shadow over my previously enjoyable pregnancy though.

How great to hear your positive stories and great outcomes. Thanks again.
