Doctor's answer:

Hello! Based on the detailed ultrasound examination of your pregnancy that you described, there is no need to be overly anxious or worried. This type of choroid plexus cyst is generally not likely to affect the fetal growth and development. Moreover, it can usually resolve on its own as the pregnancy progresses. Therefore, you do not need to undergo an amniocentesis. It would be sufficient to wait for a while and then have a follow-up examination to monitor the situation. Stay positive and wish you a speedy recovery!
