What should I do if the fetus has unilateral choroid plexus cyst?

Some pregnant women went to the hospital for an ultrasound check-up at 16 weeks of pregnancy and found that the fetus had a choroid plexus cyst on the left side, which was about 9×5 mm in size. Then when they went for another check-up at 21 weeks of pregnancy, they found that the cyst had become a little smaller. So they don’t know how harmful this choroid plexus cyst is to the body? Will it have any impact on the baby? Can the cyst be absorbed by itself? What should be done if there is a unilateral choroid plexus cyst?

Choroid plexus cyst refers to small cysts with a diameter of ≥3 mm in the choroid plexus of the lateral ventricle that are found during fetal ultrasound examination at 14 to 24 weeks of gestation. More than 90% of fetal choroid plexus cysts disappear after 26 weeks of gestation, and only a few show progressive enlargement. When a choroid plexus cyst is detected, it should be combined with other clinical data to further perform amniocentesis for amniotic fluid cell culture or umbilical cord puncture for umbilical blood culture to exclude chromosomal abnormalities such as trisomy 18 and trisomy 21. Choroid plexus cysts may also occur in normal fetuses, but most of them disappear after 26 weeks. If it does not disappear after 26 weeks and is bilateral, the baby should undergo a brain examination and a chromosome examination of the umbilical cord blood cells after birth. If it can disappear, there will be no compression and increased intracranial pressure, and the intelligence or other aspects after birth will not be affected by the "choroid plexus cyst".
