Patient's question:
Patient: Female, 28 years oldResults:
BPD (Bi-parietal diameter): 4.6 cm
HC (Head circumference): 17.6 cm
AC (Abdominal circumference): 13.6 cm
FL (Femur length): 3.0 cm
The fetal head is located above the symphysis.
Fetal heart rate: 156 beats per minute
Placenta location: Anterior and posterior walls, Grade 1
Amniotic fluid depth: Approximately 4.6 cm, with good sonority.
Due to the fetal position, the facial and cranial ultrasound could not be clearly visualized.
The fetal spine appears well-aligned, with no obvious abnormalities.
Estimated fetal weight: Approximately 282 grams.
Based on the fetal development, the estimated gestational age is around 19 weeks and 2 days.
A cystic, anechoic lesion measuring approximately 1.3 cm × 0.8 cm is observed in the right choroid plexus, with clear boundaries.
Examination complete.
Doctor's answer:
Disease Analysis: Hello, choroid plexus cysts refer to small cysts (diameter ≥ 3mm) found in the lateral ventricles of a fetus during ultrasound examination of the choroid plexus at gestational ages of 14-24 weeks. Over 90% of fetal choroid plexus cysts disappear after the 26th week of pregnancy, with only a few showing progressive enlargement. The size, number, bilateral or unilateral nature, and whether the cysts progressively shrink or disappear do not change the risk of chromosomal abnormalities in the fetus. When choroid plexus cysts are detected, further amniocentesis with amniotic fluid cell culture or cordocentesis with umbilical cord blood culture should be performed to rule out chromosomal abnormalities such as trisomy 18 and trisomy 21.Guidance: Normal fetuses can also develop choroid plexus cysts, but most of them disappear by the 26th week. If they persist after the 26th week and are bilateral, cranial brain examination and umbilical cord blood cell chromosome testing should be conducted after birth. If the cysts disappear, there will be no compression or increased intracranial pressure, and the child's intelligence or other aspects will not be affected by "bilateral choroid plexus cysts." Choroid plexus cysts beyond the 22nd week are generally considered significant. It is recommended to undergo regular ultrasound follow-ups and not to experience excessive psychological stress.
