Trisomy 21, 29 weeks

Maria Teresa Frias, MD

Buenos Aires, Argentina

This is a 35-years-old, G3,P2,  first seen at 32 weeks.

There is a slight discrepancy between the biparietal diameter (BDP: 77 mm = 29 w) and long bones (Femur: 50 mm,  humerus: 47 mm (= 27 w).

The face demonstrate a smoothing frontal area, macroglossia and micrognathia.

    

 

There was also an incidental liver calcification of 7 mm

 

Echocardiogram was normal                                                                                      

The findings suggested that this fetus had trisomy 21. This was confirmed by placenta biopsy at 34 weeks (47, XY + 21).
