Anyone know anything about these? Or know where I can get more

info?

hey trisha, i don't know anything about them, but i typed it into search on the

web and here's some websites and info i got in return(ther'es a couple at the

bottom too)...

The choroid plexus is the tissue within the brain, which produces the

cerebrospinal fluid. This fluid fills the normal spaces in the brain

(ventricles) and flows around the outside of the brain and spinal cord. Small

fluid-filled spaces, called cysts, are seen during obstetrical ultrasound

examinations in the choroid plexus in up to 2% of normal pregnancies.

These cysts disappear spontaneously during pregnancy and are, in themselves, of

no concern before or after birth. There is no need to re-scan during pregnancy.

Children with choroid plexus cysts are developmentally normal and

indistinguishable from those in whom no cysts were seen on ultrasound

examination during pregnancy.

In a few patients reported in medical journals, a fetus with choroid plexus

cysts was found to have a chromosomal abnormality, Trisomy 18. In Trisomy 18,

the fetus has an extra chromosome number 18 with a total of 47 chromosomes,

instead of the normal 46. The great majority of babies with this condition have

other physical abnormalities, often affecting the limbs (especially a clenched

fist), heart, brain, and/or face. When these defects are found in addition to

choroid plexus cysts, there is a strong concern about Trisomy 18, and the mother

would be recommended to have an Amniocentesis to determine if the fetus has this

condition.

There is considerable controversy in the medical journals about how great a risk

of Trisomy 18 or other chromosomal abnormalities there is for a fetus with

choroid plexus cysts. This is especially for the fetus that appears otherwise

normal by ultrasound and has no other risk factors; such as mother's age, a

family history of chromosome problems or an abnormal screening blood test called

(Maternal Serum Screen). The size, number and eventual disappearance of these

cysts did not alter the risk.

If a fetus with choroid plexus cysts has a detailed ultrasound, including views

of the heart and of hands that open and close, and shows no other abnormalities,

then the risk of Trisomy 18 is only 1 in about 250. The risk of an Amniocentesis

causing a miscarriage is about 1 in 250.

Maternal age (mother's age over 32) is a significant risk factor as well as

other ultrasound signs. The risk of chromosome abnormalities increases

significantly when CPC's are associated with other markers rising from less than

1 in 250 as an isolated finding in a woman under 32 years to 1 in 10 when

associated with other markers or raised maternal age.

Based on the medical literature and our experience, we do not recommend

Amniocentesis in cases with choroid plexus cysts as the only risk factor. We do

believe, however, that Amniocentesis is certainly not inappropriate and can

justifiably be performed because of parental concern, even for a small isolated

choroid plexus cyst.
