Possible turners syndrome!?

I went for my scan Friday where I should have been 13 weeks and they said there is fluid around my babies neck (cystic hygroma s) which could be something called turners syndrome? It's a 50/50 chance, I've have researched it and some cysts disappear according to some parents and they're baby is born healthy,also only happens to girls, has anyone else been told this at all???  If you look you can see when the head is and where the neck should be :(
