What does the liquid dark area in the fetal posterior fossa cistern mean?

Patient's question:

Last month's check showed a separation of 0.88 cm in the posterior horn of the left lateral ventricle of the fetus. Today's check revealed 1.0 cm on the left and 0.84 cm on the right, with a deep 1.0 cm liquid shadow observed in the posterior fossa. Can this be absorbed on its own?

Doctor's answer:

Hello, the posterior fossa cisterna shows a liquid dark area, considered to be less than 1 cm, which is normal. You can have regular follow-up examinations. We know that hydrocephalus in children can cause significant harm to them. If it is not treated in time or if the treatment method is incorrect, it can progress rapidly and bring great harm to the child. Therefore, it is important to seek professional medical treatment promptly at a regular hospital. This is the key.
