Choroid plexus cyst might seem scary when mentioned by your technician, especially at your second trimester. You might even start thinking of the worst possible cases.
Choroid plexus cysts also known as CPCs are very popular and are usually seen in 1 to 2% of fetuses when an ultrasound is being carried out. They might sound dangerous, but a lot of them are considered harmless boils of fluid that are found inside the brain but can go before a baby is born.
In the course of this article, we will give 7 great facts that parents need to know in order to stop being afraid and get clear facts too.

- From a huge neonatal study, 8.8% of babies with choroid plexus cysts had it disappear by 6 months.
- CPCs are mostly found in 1% of a lot of pregnancies, and there have been some reports that are 3.5%.
- Almost 95% of choroid plexus cysts go by the gestation period of 26 to 28 weeks.
You are in the normal range if your child’s cysts are 3 to 5mm and it was discovered at 20 weeks. You should plan ultrasounds between the 24 to 28th week just to be sure.
Choroid plexus cysts build as clear fluid gets into the choroid plexus. They tend to look like small blisters that are filled with fluid.
If you are trying to imagine them, they look like small bubbles that are created while the baby develops and it then gets sucked back in, which is a normal step in the development of a fetus.
A lot of them go away by the third trimester, and they don’t bring about symptoms.
Choroid plexus cysts are seen as a subtle marker for Edwards syndrome, but it is only when there is an availability of anomalies.
- When there is a presence of anomalies, the issue rises but choroid plexus cysts on its own doesn’t entail anything serious.
- If proper ultrasound isn’t used to discover it, the issue of disorder in chromosomes still lies in the percentage of 1 or 0.3.
In the case that the age of the mother is under 35, and the tests are normal, there is low risk
In the case that choroid plexus cysts are found out in the second trimester, this is what is required:
- Level 2 ultrasound checks out the kidneys, heart, limbs, spine, and brain for anomalies that are structured.
- When there is talk about screening for maternal serum, choices are made up of quad screen or NIPT.
- If there is no availability of extra markers, a lot of experts would advise against testings that are invasive.
- There is no necessary check up, if there is a presence of small risk.
There will only be a provision of regular amniocentesis if the mother’s age is high or other discoveries.
There is usually a high rate of developmental health in new babies.
- According to a study of 2,111 babies, CPCs was found in 186. By the time it got to 6 months, a lot of them were solved. Further findings depicted a normal developmental health in every child that was tested.
- Findings from another health provider in India saw that there were 67 choroid plexus cysts cases, before giving birth, there was a resolution of 94%, and a lot of those babies had zero motor issues.
Lastly, there are no issues in the long run and no unique treatments required.
These are the following symptoms that might require more check up:
- Huge cysts that are greater than 1cm or different bilateral cysts
- Mothers over the age of 35
- Strange outcomes from screening tests
- Various other issues from ultrasound such as limb issues, heart issues, and slow development
In the above cases, it is proper to use the options of NIPT and genetic counseling. In cases where it is just the CPCs, especially if it is screened normally, a lot of health providers see it as harmless.
In the case that you feel stressed out:
- Think of going for genetic counselling so that you don’t feel confused
- Request for a level 2 scan from your doctor
- Be dependent on further ultrasounds usually between 24 to 28 weeks to discover changes
- Talk about how the outcomes from screening made you feel
Note down three main questions for your health provider during your next check up. That will help to suppress anxiety.
No. CPCs are harmless fluid blisters and they don’t affect brain growth. They shouldn’t be seen as tumors.
No, not really. The little, or unilateral cysts usually have the same results. There should only be alarm when the cysts are big or bilateral and accompanied with strange symptoms.
Not really. They are mainly connected to Edwards syndrome. But there is no solid link to Edwards syndrome if there is no presence of markers.
It is very rare. When a cyst is big, it can block the flow of CSF but it is not popular. A lot of them go away by themselves and never show signs.
No. Further scans and growth checks depict that children that were birthed with just choroid plexus cysts grow in a normal way. There is no need for a special treatment.
A choroid plexus cyst might sound like a big deal but mostly, it is just a temporary, benign discovery that goes away before giving birth. The only sole cases that need deeper check up is in about 1 in 300.
You should be fully aware that others go through this too. You need to erase your worries by gaining information. Ask the right questions and believe that a lot of choroid plexus cysts don’t mean danger.
