Case report
A 35-year-old woman (G1P0) with unremarkable medical history presented to our unit at 20 weeks 4 days of gestational age. She has done neither the first nor the second trimester screening tests for aneuploidies. Amniocentesis was not performed due to threatened miscarriage until 18 weeks.
Our examination found a complete atrioventricular septal defect (AVSD) of the fetus. Furthermore, pulmonary artery looked small and aorta looked overriding the VSD suggesting an associated tetralogy of Fallot. Long bones were short (below 5th percentile). Macroglossia was also present, although in resting tongue it was not very evident.
Amniocentesis was performed and the QFPCR technique revealed a karyotype 47,XX+21. The couple opted for termination of pregnancy.
Images 1, 2, 3, and 4: 20 weeks, 4 days of gestational age. The images show sagittal scans of the fetal head with macroglossia, which is evident predominantly in the sticking out phase of the tongue (Images 1 and 2 - the tongue is highlighted by white color on the image 2). During the resting phase (Images 3, 4) the macroglossia was not so evident.
