Case report
This is a 16-year-old woman (G1P0), referred to our antenatal unit at 24th week for skeletal anomalies. Her medical history was unremarkable. Our ultrasound investigation revealed:
Intrauterine growth retardation with normal amniotic fluid volume
Abnormal fetal profile with micrognathia
Abnormal position of hands with possible syndactyly of the third and fourth fingers of the left hand
Clubbed feet
Generalized fetal akinesia with fixed position of several joints
The serological tests were negative (TORCH and Chikungunya infections) an the karyotype was also normal (46, XX). The anomalies were consistent with the distal arthrogryposis multiplex congenita. The parents opted for termination of the pregnancy. Postmortem radiography showed the hyper-flexed multiple contractures of the joints of the upper and lower extremities. The elbows were in fixed flexion. The parents refused autopsy.
