What are the causes of choroid plexus cysts

Many pregnant women will become overly nervous when they find out that their fetus has a choroid plexus cyst. In fact, there is no need to be nervous, because choroid plexus cyst is a very common condition and will gradually disappear in the later stages of pregnancy. Now let’s look at the causes of choroid plexus cysts.

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".

Causes of Cysts

1. Genetic genes According to statistics, 25% of ovarian tumor patients have a family history, which shows that ovarian cysts have genetic genes;

2. Endocrine factors: Although the ovaries are small, they are important organs for producing eggs and ovulating, secreting endocrine hormones, and balancing endocrine system. Ovarian tumors often occur during the reproductive age when the endocrine system is active.

3. Lifestyle factors: Long-term dietary structure, bad living habits, and excessive psychological pressure cause excessive acidification of the body, a decline in the overall function of the human body, and the development of abnormal proliferation of ovarian tissue, eventually leading to ovarian cysts and even cancer.

4. Environmental factors: The incidence of ovarian cancer is high in industrially developed countries and among upper-class women. Food contamination is related to high cholesterol in the diet.
