Figures & Tables

Fig. 1.

Fetus at 35 weeks of gestation. (A) T2-weighted magnetic resonance imaging (MRI) sequences demonstrate the uterus with a thick myometrial ring separating it into two segments (arrows). The right arm is entrapped in the lower uterine segment (asterisk), with part of the amnion in constant contact with the right axilla (b – bladder). (B) T2-weighted images demonstrate the difference between the left arm (black arrow) and the right arm (white arrow). The right arm shows a hyperintense signal in the subcutaneous tissue, corresponding to localized skin edema. (C) Three-dimensional reconstruction of MRI images of the fetus. The fetal forearm shows edema (blue) and is restricted to the lower uterine segment. (D) Ultrasound image showing the amniotic membrane (white arrows) originating from the uterine constriction ring (arrowhead), rupturing and infiltrating the fetal skin, with striated hypoechoic fibers. (E) Postnatal image of the neonate at the first week of life, showing the scar resulting from the lysis of the amniotic band
