Amniotic band

Case contributed by Dr Mostafa El-Feky


Routine scan.

Patient Data

Age: 30 years
Gender: Female


A loose amniotic band is noted extending from the placental surface (image 1) reaching inbetween fetal legs (image 2). Scanning of fetal limbs is normal for gestational age.

Gestational age is about 15 weeks and 5 days.

Case Discussion

This case shows a free-floating thread with an intact chorionic membrane, representing an amniotic band. It can lead to amniotic band syndrome. So, careful examination of fetal limbs is necessary.

Differential diagnosis is amniotic sheet which is a shelf-like indentation of the amniotic sac made by uterine synechia. It is not associated with fetal anomalies.
