Cyst on umbilical cord

L

Has anyone had a cyst on the umbilical cord? At my first ultrasound (I was 9 weeks) the tech found a cyst on the umbilical cord but didn’t seem too worried about it. She said they usually disappear by the next scan at 12/13 weeks. Just wondering whose had experience with this? I’m doing my genetic testing on Friday. Just hoping this cyst disappears. With anyone whose cyst did not disappear - what does that mean? I’ve read different things so I’m just curious what others have experienced. Thanks!
