choroid plexus cysts / 19 week ultrasound

[jenni__]

I need some advice support anything. My ultrasound results came back and it shows the baby has a
choroid plexus cyst it's small in the brain. Apparently it is common and goes away. They told me not to be concerned since my bloodwork came back all negative for all my tests for downs, any abnormalities etc. Anyone else had this? Or know anyone that has? I am trying to stay calm but I'm freaking out. They said everything else with the baby is growing normal.. But I don't know what to think. They said no need for a follow up ultrasound.

Thanks! My doctor said I don't need a follow up and will not book me one because my baby will be fine according to him. I am actually moving provinces from alberta to British Columbia so I meet with a new doctor out there next week. Going to ask her if she will send me .

Don't stress over it. But I'd go for a follow up anyways, just to ease the mind. My blood work came back abnormal for trisomy 18 with a 1 in 91 chance my baby would have it. Went to the doctor's for an ultrasound and the baby was absolutely perfect, doctor said she's growing and developing perfectly. Put my odds at 1  in 800. Point is, don't stress over it! :)

From wikipedia-

During embryological development, some fetuses may form choroid plexus cysts. These fluid-filled cysts can be detected by a level II ultrasound (18–20 weeks gestation). The finding is relatively common, with a prevalence of ~1%. Choroid plexus cysts (CPC) can be an isolated finding, which confers a 1% (variable based on population studied) risk of fetal aneuploidy. The risk of aneuploidy increases to 10.5-12% if other risk factors or ultrasound findings are noted. The particular size, bilaterality, disappearance/progression or the position of the CPC, do not have any effect on the risk of aneuploidy. 44-50% of Edwards syndrome (trisomy 18) cases will present with CPC, and 1.4% of Down syndrome (trisomy 21) cases will present with CPC. ~75% of abnormal karyotypes (obtained by chorionic villus sampling or amniocentesis) associated with CPCs are trisomy 18, while the remainder are trisomy 21.[2]

CPCs typically disappear later during pregnancy, and are considered soft markers. They are usually harmless, and studies have shown that they have no effect on infant and early childhood development.[3]
