Case report

A 23-year-old woman (G1) was referred to our antenatal unit at 22 weeks of her pregnancy due to a unilateral fetal hand anomaly. Her family history of skeletal congenital diseases was negative. At 13 weeks the fetus was scanned by ultrasound, but at that time no anomaly was found. Another scan was done at 22 weeks and the adactyly of the right hand was detected. Karyotype of the fetus was normal (46, XY). The patient opted for the termination of the pregnancy and the diagnosis was confirmed.

Images 1, 2: 22 weeks of pregnancy; the gray scale images show the normal left upper extremity (image 1) of the fetus and the right one with adactyly (image 2).

Images 3, 4: 3D images comparing the normal left hand of the fetus (image 3) and the right one with adactyly (image 4).

Images 5, 6: The image 5 represents a postnatal X-ray of the fetus showing the adactyly of the right hand (the arrow specifies the fifth metacarpal bone). The image 6 shows a pathological specimen of the fetus with the adactyly of the right upper extremity.
