###Human: I am 34 weeks pregnant with choroid plexus cyst in fetus. Will it cause Down syndrome? ###Assistant: Hello. I was able to see the images and reports. (attachment removed to protect patient identity).  Apart from the cysts they have not reported any frank worrying features. The nasal bone and face profile images are not very clear. In Down's, the nasal bone may be absent or hypoplastic. The other direct features associated with Down’s are hypertelorism or widely spaced eyes which is not seen in your scans. There is no neck fold thickening. Therefore at this stage of pregnancy, I would ask you not to stress out. Just make sure that on your next scan the sonographer is aware of the choroid plexus cysts finding and includes cardiac evaluation and facial evaluation in detail. Take care.
