At my 20 week ultrasound the tech pointed out to the OB an area of concern near the point of entry of the umbilical cord, and said it was possibly an umbilical hernia or omphalocele. It's very small though, he made a point of saying that he had seen some far bigger. So he sent me to the hospital to have another Level II ultrasound, which I had yesterday, and I got the same feedback from the MFM doc, who explained it could be either, that with an ultrasound you can't discern between the two. I knew from my research before the appt that umbilical hernias are pretty benign, and usually heal on their own in the first year. But omphaloceles require surgery to fix. What I didn't expect is when she told me that it can be associated with other abnormalities and chromosomal defects. I had done the Materni21 test, and everything looked fine, the nuchal test at 13 weeks and everything looked fine. She tells me that they aren't 100% accurate, like an amnio would be, which she recommended but I am not keen on. I do not want to do anything invasive that could cause a miscarriage, especially when we have no idea if it even is an omphalocele. She also recommended a cardiac echo of the baby to check for heart abnormalities, I think because it's the most common one that overlaps with an omphalocele if Down's is involved. That I will do. Baby is growing well and measuring a little big for it's age, so there aren't any other red flags there.
Has anyone else had this experience? Waiting to hear back from my regular OB to get his opinion.
