Diagnosis by real time ultrasound of hourglass herniation of the fetal membranes. Two case reports.
We present two patients in whom hourglass herniation of the fetal membranes through the cervix occurred at 26 weeks gestation. The diagnosis was made by real time ultrasound and led to conservative management. One of the infants survived and might well not have done so without conservative management.
