Question 1

how serious are bilateral choroid plexus cysts in fetus?

Accepted Answer

Usually normal: Most babies with choroid plexus cysts in the brain are normal, and almost all cysts go away by the end of the second trimester.  But cysts can also be a marker for a problem called trisomy 18, which means an extra chromosome 18 in every cell of a baby's body.  A maternal fetal medicine doctor can do an ultrasound and look for any other sign of trisomy 18.

Question 2

therere are choroid plexus cysts on my baby's ultrasound. does that mean holes in the brain? what else?

Accepted Answer

Usually benign.: The choroid plexus is a normal structure in the fetal brain, that makes the cerebrospinal fluid.  Cysts can appear and disappear within the choroid and it usually is normal, but if there are a lot of cysts then testing for down's or similar syndromes may be a good idea.

Question 3

aged  32, 20 week preg, found fetal choroid plexus cyst during ultsound, doc recommended materni21 plus test, awaiting result, scared as hell.y the cyst?

Accepted Answer

Probably normal!: Up to 0.3-3.6% of all fetuses will have choroid plexus cysts noted during screening prenatal sonography. Most of the time this is an incidentaloma of no clinical significance (normal babies have this all the time). Occasionally it is associated with fetal trisomy 18 or edwards' syndrome - a severe/lethal fetal anomaly - however additional problems are typically seen in such cases. Maternit21 ok!

Question 4

my doctor just detected a fetal choroid plexus cyst at 28 weeks. should i be worried?

Accepted Answer

Probably not: Most of these are of no real consequence.  If large and diverted significant blood flow from the fetus, it is possible to see some effect but this is rare.  They can be seen even in the first trimester and likely just represent vascular anatomical variation of the placenta.

Question 5

can there be other abnormalities in a fetus with choroid plexus cyst?

Accepted Answer

Downs Syndrome: It is very rare for a choroid plexus cyst to be associated with more significant abnormalities.  Here is link with more information:

Question 6

at my 20 week us i was told my baby has a choroid plexus cyst and a small fetal stomach.  odds of trisomy 18? f/u is in 4 weeks for routine us.

Accepted Answer

Blood test: The risk of trisomy 18 is assessed by doing blood genetic testing. A triple, quad or penta screen or alternatively fetal dna sequencing. If the blood test is normal then the presence of a unilateral choroid plexus cyst does not increase the risk of t18. If t18 is abnormal then a unilateral choroid plexus cyst can be supportive evidence.

Question 7

can someone explain brain mri findings? - some prominence of the atria of the lateral ventricles, right greater than left, which appears stable and may be related to cysts at this location, involving the region of the glomus of the choroid plexus?

Accepted Answer

: Taken at face value, your images are benign and represent no worrisome lesions

Question 8

is there any correlation between the presence of a choroid plexus cyst at mid-pregnancy and autism?

Accepted Answer

Seems Not: There is no obvious association, as many non autistic situations have this happen.

Question 9

does a father with choroid plexus cysts have an increased chance of fathering a child with genetic challenges?

Accepted Answer

Genetic  mutations : With choroid plexus cysts have other physical manifestations as well, according to the data base i reviewed. If you are concerned, ask your wife's ob/gyn for pre-pregnancy counselling by a prenatal genetic counselor to review your family history &your medical history. A chromosomal microarray ordered from  lineagen at (801) 931-6224 can be done with a buccal swab kit that they send to the doctor.

Question 10

is there a link between choroid plexus cysts and trisomy 18?

Accepted Answer

Trisomy 18: The presence of choroid plexus cysts and other anomalies can be caused by the presence of trisomy 18 in the fetus. A solitary choroid plexus cyst is not usually associated with trisomy 18.
