What does bilateral chonid plexus cysts means?
Choroid plexus cysts (CPCs) are pockets of fluid that develop in the Choroid Plexus, which are bilateral cavities located at the base of the brain near the ventricles. These cavities contain fluid which bathes the spinal cord (via the ventricles) and the brain itself. During a sonogram, a technician will look for any dark spots in the choroid plexus, which indicates a dense mass of fluid or a cyst. Any cyst above 10mm in the second trimester is cause for concern. The fetus’ brain begins to develop at the beginning of the 24th week of pregnancy, which may have a link to why the cysts resolve themselves by the 26th week.
