What to do if you have a left choroid plexus cyst

When it comes to cysts, I think most people in real life are familiar with them. Left-sided choroid plexus cyst is the term that pregnant women are most likely to encounter and fear the most. After all, everyone hopes that their baby will have no problems. Left-sided choroid plexus cysts occur most frequently between 14 and 24 weeks of pregnancy. They are a type of cyst and are usually less than 3 cm in diameter. So how should we effectively deal with left-sided 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".

Clinical manifestations

Small cysts with a diameter of ≥3 mm are found scattered in the choroid plexus of the lateral ventricle during fetal development 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. If it does not subside after 26 weeks, the baby may experience compression and increased intracranial pressure after birth.

examine

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. 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.

diagnosis

1. Cystic dark areas are seen within the strong echo of the choroid plexus, with thin cystic walls, smooth and neat edges, and mostly round in shape. Cysts can be single or multiple.

2. Dynamically observe the size of the cyst. If the cyst is less than 1 cm or getting smaller, the possibility of chromosomal abnormality is small. At the same time, attention should be paid to checking whether there are new malformations in other parts. Sometimes after the choroid plexus cyst is detected by ultrasound, other malformations cannot be detected. However, some scholars believe that the size, number, bilaterality or unilaterality, and whether the choroid plexus cyst is progressively reduced or disappears will not change the risk of the fetus suffering from chromosomal abnormalities. When a choroid plexus cyst is detected, amniocentesis for amniotic fluid cells or umbilical cord blood culture should be performed in combination with other clinical data to rule out chromosomal abnormalities such as trisomy 18 and trisomy 21.

Prognosis

Simple choroid plexus cysts often have no clear pathological significance and have a good prognosis, but fetal choroid plexus cysts are associated with an increased risk of chromosomal abnormalities (trisomy 18, trisomy 21, etc.).
