Patient's question:
Posterior fossa cistern shows a liquid dark area with a depth of about 0.7 cm after 27 weeks of gestation. Is it dangerous?Doctor's answer:
Hello! Enlargement of the posterior fossa on ultrasound may indicate the possibility of hydrocephalus, but it cannot be diagnosed as hydrocephalus. Experienced ultrasound doctors will compare relevant factors to make a well-founded diagnosis. Mild abnormalities discovered during pregnancy can be confirmed through dynamic observation. Regular prenatal check-ups are important. If the enlargement of the posterior fossa does not exceed 1 cm, it is generally not a major issue. In your case, dynamic observation can be initially considered. Wishing you good health!
