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 we
eks 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 s
ection. 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 rapture
and hemorrhage during vaginal delivery.
