ad. 14. Choroid plexus cysts. What does it mean?

Cysts are a kind of widening of choroid plexus. Choroid plexus cysts are not a brain defect on their own, and as an isolated characteristic, are a part of the physiology of fetal development. For this reason, they do not require a second opinion and they disappear usually around 26 weeks of pregnancy.

If a sonologist diagnoses choroid plexus cysts, he is obliged to perform a more detailed assessment. It is essential to verify whether there is spasticity of hands (hard-clenched hands during the whole examination), umbilical cord cyst, umbilical hernia and heart defects. Coexisting with these symptoms might indicate a genetic syndrome (e.g. trisomy 18) and it requires performing additional tests.
