Choroid plexus cysts are relatively common and are often identified during routine prenatal ultrasound examinations. The prevalence of choroid plexus cysts varies depending on the population being studied and the criteria used for diagnosis.
In general, choroid plexus cysts are more frequently observed during the second trimester of pregnancy. They are estimated to be present in approximately 1-2% of all prenatal ultrasounds. It is important to note that the majority of these cysts are isolated findings and not associated with any significant health issues or genetic abnormalities.
Choroid plexus cysts are more commonly observed in female fetuses compared to males. They are also more prevalent in pregnancies with advanced maternal age, particularly for women over 35 years old.
While choroid plexus cysts are relatively common, it's important to remember that the vast majority of these cysts are benign and resolve on their own without causing any complications or long-term effects. However, if other abnormalities or markers are present, further evaluation and monitoring may be recommended to ensure the overall health and well-being of the fetus. Consulting with a healthcare professional, such as an obstetrician or a genetic counselor, can provide more specific information based on individual circumstances.
