At my twenty weekend scan, I found out the baby had an isolated choroid plexus cyst. Apparently this is no danger if it is on its own and not accompanied by further cysts. I am due for a further scan at 24 weeks to see whether it is still there as apparently 95% of the time they disappear by 24 weeks. Nonetheless, it is worrying. Has anyone experienced having one? If it did not go biy the birth, was your baby alright?
