Patient's question:
At 32 weeks, biparietal diameter (BPD) is 86mm, head circumference (HC) is 309mm, femur length is 60mm, abdominal circumference (AC) is 280mm. Today's check revealed that the head circumference is two weeks larger than expected, and it is recommended to recheck for hydrocephalus. I would like to ask if hydrocephalus is severe? My menstrual cycle is irregular, and my last menstrual period was on December 10th. The doctor calculated my estimated due date as October 30th based on earlier ultrasound and NT results. The Down syndrome screening showed low risk, and the 4D ultrasound was normal. At 25 weeks, the head circumference was 241mm during the 4D ultrasound. Could you please help me check if it is normal and whether it will affect the baby's health? Thank you.Doctor's answer:
Hello, I'm glad to assist you: In this case, the biparietal diameter appears slightly larger at the moment. However, if your menstrual cycle is not very accurate, it doesn't matter much. Especially for the tests mentioned above, they are generally normal in the early stages. I suggest that since you are already 32 weeks pregnant, you can only wait and see. Because the possibility of hydrocephalus in this case is not high, as long as the child's other development is good.
