Patient's question:
NoDoctor's answer:
Enlargement of the fetal posterior fossa cistern suggests the possibility of fluid accumulation. If the fluid volume is less than 10 millimeters and the fluid gradually decreases, disappears, or remains unchanged during regular follow-up, it may be considered a normal variation with no significant impact on the baby's future development, and pregnancy can continue. For cases where the fluid range is between 10 to 14 millimeters, it is necessary to first rule out the presence of other congenital anomalies and chromosomal abnormalities (fetal brain CT, umbilical cord blood).
