Introduction
Fetal bilateral choroid plexus cysts may be caused by physiological factors or pathological factors such as chromosomal abnormalities and congenital malformations, which require targeted treatment. During the second trimester of pregnancy, rapid development of vascular structures in the fetus may lead to impaired normal expansion of the ventricular choroid plexus vessels, resulting in fetal bilateral choroid plexus cysts.
Fetal bilateral choroid plexus cysts may be caused by physiological factors or pathological factors, such as chromosomal abnormalities and congenital malformations, which require targeted treatment. The specific analysis is as follows:
I. Physiological Factors
During the second trimester of pregnancy, rapid development of vascular structures in the fetus may lead to inadequate expansion of the ventricular choroid plexus vessels, resulting in fetal bilateral choroid plexus cysts. However, this condition typically resolves spontaneously with further development of fetal organs and tissues in the late stages of pregnancy and does not require special treatment.
II. Pathological Factors
1. Chromosomal Abnormalities
If chromosomal abnormalities exist in the fetus due to poor sperm quality or abnormal fertilization, the aforementioned symptoms may occur during fetal development in utero. In such cases, amniocentesis should be performed promptly to identify the specific chromosomal arrangement issues, followed by appropriate treatment.
2. Congenital Malformations
If ultrasound examination reveals that the fetal bilateral choroid plexus cysts are caused by congenital malformations, relevant interventions should be sought at a qualified medical institution. In some cases, termination of pregnancy may be necessary.
It is recommended to undergo regular prenatal checkups during pregnancy and maintain a positive and relaxed mood.
