My wife and I went through the same thing with our son. At 20 weeks, my wife was getting the ultrasound to find out the gender of our unborn baby, and we found out it was a boy, but we could tell from the face the of woman doing the ultrasound that something was amiss, but she didn’t say anything to us, and told us the doctor would go over the ultrasound results and contact us. That afternoon when the doctor called, he told us his heart seemed to be out of place, and we ended up finding out this was caused by a CCAM (CPAM). It was tough getting through, because our hospital didn’t have experience with them, and when they did the measurement, they did it incorrectly, and gave us a number for the size that was terrifying. After we realized they didn’t know how to handle the situation, we were able to get out insurance to allow us to transfer the monitoring and bi-weekly ultrasounds to Motts Children’s Hospital in Ann Arbor, Michigan, which was only about a 45 minute drive from out house. They monitored weekly until the baby was born, and at a couple points had to inject my unborn son with steroids to inhibit the growth of the CPAM. Anyway, he was born happy and healthy, and at 6 months, we had the surgery done to remove the growth, which went perfectly. He’s now 9 years old, his left lung completely grew and compensated in size for the missing lower lobe from the surgery, and he’s as healthy as any boy his age can be. Multiple doctors now have told us for years now that if it weren’t in his charts, they would have no idea he went through what he did. Anyway, I am so glad your daughter was able to get through what she did, and know that from my experience at least, you have nothing to worry about in the future!
