Is A A Bilateral Plexus Cyst At 19 Weeks Of Pregnancy In The Fetus Brain A Serious Concern?
I am 31 years old 21 weeks pregnant. My Dr found a bilateral plexus cyst at 19weeks U/S in the fetus brain with no other markers in my first or second ultra sound. My blood test are normal, and my doctor is not sending me for more testing, however I am very worried. Do I need to do more ultrasound or Amniotic test?
Suggestive of choroid plexus cysts of the fetal brain. Advised further evaluation. The brain contains pockets or spaces called ventricles with a spongy layer of cells and blood vessels called the choroid plexus. It is in the middle of the fetal brain.
Choroid plexus cysts are present in one to two percent of normal fetuses. In the vast majority of cases, the cysts resolve or disappear and have no consequences. However, in a very small percentage of fetuses with choroid plexus cysts, there is an associated chromosome disorder called trisomy 18. Fetuses with trisomy 18 have an extra copy of chromosome, 18 and most of the time they are stillborn.
So, in view of the above, I advise you to consult your doctor for further evaluation and to undergo certain tests such as alpha-fetoprotein (AFP) test, Targeted Imaging for Fetal Anomalies (TIFFA) scan or amniocentesis to be done to rule out the chance of trisomy 18 or Down syndrome.
Hope I have answered your query. Let me know if I can assist you further.
Regards, Dr. Mohammed Taher Ali
