Fetal choroid plexus cysts, is it necessary to do an amniocentesis?

Patient's question:

At 24+4 weeks of pregnancy, a 0.60.5 cm anechoic area is visible on the right side of the fetal choroid plexus. The results of the Down syndrome screening are normal. All other indices are normal.

Doctor's answer:

Analysis of the condition: Hello, choroid plexus cysts refer to small cysts with a diameter of ≥3mm that are scattered and found in the ultrasound examination of the lateral ventricles during the development of a fetus at gestational age between 14-24 weeks. Over 90% of fetal choroid plexus cysts disappear after the 26th week of pregnancy.
Recommendation: It is recommended to have a follow-up examination after the 26th week. If the cysts disappear, there will be no compression or increased intracranial pressure, and the child's intelligence or other aspects will not be affected.
