Enlarged Ventricles or Partial ACC?

El

Doctor found slightly enlarged left ventricle (10.7mm) at 26 week growth scan, also concerned he couldn't get a good view to see if the corpus callosum was present. He doesn't want to do the MRI until after another ultrasound (this Thursday) to see if he can get a better picture and if ventricle size has changed. Is anyone else dealing with this now? I'm trying to stay positive, but worried for my little boy.
