Question
At 9 months of pregnancy, an examination found the width of the cerebellomedullary cistern in the fetus to be 1.2 cm. Ask if this condition will improve.
Answer
Apart from the slightly widened cerebellomedullary cistern in the fetus, if other indicators are normal, it is recommended to have regular ultrasound checks to further clarify the diagnosis. It is important to closely follow up and observe any changes. If there is progressive enlargement of ventricular dilation, it may indicate hydrocephalus. Normally, after 20 weeks of pregnancy, the ratio of the distance from the lateral ventricle to the midline to the distance from the midline of the brain to the skull plate (ventricular ratio) should be less than 1/3. If it is greater than 1/3, it may suggest the presence of hydrocephalus. It is recommended to visit a regular hospital for regular ultrasound checks to further clarify the diagnosis.
