Background:
There are several types of intrauterine membranes; most are not associated with any deleterious effect on fetal outcome.
Case:
An unusual placental insertion was diagnosed sonographically at 23 weeks of gestation. It consisted of two distant placental insertions into the uterine wall, with a large placental mass between them floating freely in the uterine cavity. Normal fetal growth pattern and blood flow indices were found. A normal female neonate was delivered via low transverse cesarean section. There were no macroscopic or microscopic placental anomalies.
Conclusion:
This case raises several questions: the right mode of delivery, frequency of ultrasound follow-up and possibility of placental band rupture and hemorrhage during vaginal delivery.
