Case of the week #106
October 31-November 13, 2003
François Duchatel MD
CHU Pontoise, France
A 25-year-old patient, G3, P2, is treated by her physician at 9 weeks 2 days of gestational age.
An amniocentesis was performed at 19 gestational weeks. The alpha fetoprotein was at 1194mg/1 (n < 3250 mg/1), the acetylcholinesterase normal.
An ultrasound performed at 20 weeks 3 days demonstrates teh following images. The biometry is normal, between the 30th and 40th percentile.


Ten days later, at 21 weeks 4 days, neither of the findings above could be seen.
An ultrasound performed at 24 weeks 3 days is normal with a biometry between the 25th and 30th percentile. No limb anomalies are noted.
At 29 weeks, the biometry is between the 10th and 40th percentile. The following are images of the feet. No fetal breathing is noted.






At 31 weeks, a male fetus was born under peridural anesthesia, weighing 1350g (which is in the 30th percentile for the age). The head perimeter is 302mm, which is between the 50th and 90th percentile for the age. The Apgar was 1 at 1 minute. The child was intubated and put on a ventilator immediately, cared for by the neonatal intensive care unit.
