I am so worried and due to see a specialist next week but I was wandering if anyone could offer any information. The 20 week scan revealed 2 cysts on babies brain. She said she could also not see the hands or the feet clearly. I thought I saw a weird shape head but didn't comment on it at the time because it only made sense that is could be a marker for T18 once I'd done some research. Should i be concerned about the hands and feet... do most 20 week scans show them clearly?
