(CNN) — Margaret Boemer went for a routine ultrasound 16 weeks into her pregnancy with her third child. She quickly found out that things were far from routine.
"They saw something on the scan, and the doctor came in and told us that there was something seriously wrong with our baby and that she had a sacrococcygeal teratoma," the Plano, Texas, mom said in an interview shared by Texas Children's Hospital. "And it was very shocking and scary, because we didn't know what that long word meant or what diagnosis that would bring."
