Case report

This is a case of the first pregnancy of a 36-years-old patient. She conceived spontaneously after 6 years of infertility. Personal and family history were unremarkable.

First ultrasound examination was performed at 7 weeks of gestation. The crown-rump length corresponded with the duration of amenorrhea. At the ultrasound examination at 12 weeks, we revealed a hygroma colli and generalized subcutaneous edema associated with a single umbilical artery. No other anomalies seemed to be present. Cardiac examination did not show any anomalies. The crown-rump length was normal.

Patient underwent a chorionic villous sampling the day after the ultrasound examination. Both the preliminary and the definitive result showed a normal female karyotype.

The subsequent scan was performed 10 days later. We noticed a slight regression of the hygroma but further dilation of the jugular sacs was evidenced.

The couple opted for pregnancy termination. The karyotype of the aborted fetus showed a normal female karyotype, 46 XX. The autopsy was not performed.
