Patient's question:
Gestational age 32 weeks, fetal head circumference standard on ultrasound report, head circumference 586mm, will it be too large? Previous treatment history and effectiveness: Gestational age 32 weeks, fetal head circumference standard on ultrasound report, head circumference 586mm, will it be too large? What kind of help do you want: Gestational age 32 weeks, fetal head circumference standard on ultrasound report, head circumference 586mm, will it be too large?Doctor's answer:
At 32 weeks of pregnancy, the biparietal diameter is 8.0 mm, the femur length is 62 mm, the head circumference is 290 mm, and the abdominal circumference is 279 mm. Based on your description, your baby's head circumference is larger than average. The reason for reduced head circumference is congenital cerebral cortex thickening or gliosis, which leads to abnormal brain size reduction. In clinical practice, the main cause of reduced head circumference in children is hydrocephalus, where the excessive fluid is medically referred to as cerebrospinal fluid. The basic feature of hydrocephalus is the production of intracranial hypertension due to excessive cerebrospinal fluid, causing the normal intracranial space to expand. The reduction in head circumference is the most vulnerable feature. It is recommended that pregnant women seek follow-up consultation in the obstetrics and gynecology department of a tertiary hospital promptly.
