This is a 28-year-old woman (G2P1), referred to our antenatal unit at 13 weeks of pregnancy. Our ultrasound revealed septate cystic hygroma, generalized subcutaneous edema, hydrothorax and ascites of the fetus. Hypoplastic left heart was also discernible. Hyperechoic interventricular cardiac septum was visible.
Subsequent chorionic villus sampling revealed 45X0 karyotype. The pregnancy was terminated and pathological study found mitral dysplasia and aortic coarctation of the fetus.
Images 1, 2, and 3: 13 weeks of pregnancy; the images 1, 2 show 2D transverse scans of the fetal head with massive cystic hygroma and choroid plexus cysts (image 2). The image 3 shows 3D scan of the fetal head with cystic hygroma (arrows).
