18) The presence of hypointense, irregular intraplacental
bands on T2-weighted sequences, analogous to the vascularized lacuna seen on ultrasound, is strongly associated with abnormalities of placentation.
signal, due to hemorrhage or vascular lacunae (9);
The paired umbilical arteries connect with each other inside the placenta and subsequently branch into chorionic arteries or intraplacental
The common MRI features suggesting placenta accreta are as follows:[sup] (1) Uterine bulging, especially into the region of the scar or bladder; (2) heterogeneous signal intensity within the placenta; and (3) dark intraplacental
bands on T2-weighted imaging.
These are: abnormal uterine bulging of the normal pear-shaped gravid uterus, heterogeneity of the signal intensity of the placenta on T2-weighted images and the presence of T2-weighted dark linear bands in intraplacental
signal intensity, extending from the basilar plate to the placental surface.
Essential role of platelet--derived growth factor receptor Alpha in the development of the intraplacental
yolk sac sinus of Duval in mouse placenta," BiolReprod, Vol.
Our case was very uncommon in its presentation with marginal sinus and intraplacental
choriocarcinoma: clinical and pathologic features of seven cases (1967-1996) and discussion of the differential.
Abnormalities such as infarcts and hematomas might create a hypoxic intraplacental
environment that stimulates vasculogenesis and predisposes these infants to postnatal hemangioma growth, said Dr.
ULTRASOUND DIAGNOSIS: Chorioangioma is usually depicted as a well circumscribed intraplacental
mass with a complex echo pattern.
choriocarcinoma: experience from a tertiary referral center and relationship with infantile choriocarcinoma.
Additionally, to achieve a better understanding of the nature, pathogenesis, and role in pregnancy outcome of placental HEV, we evaluated the clinical implications of increasing degrees of severity and examined the interplay of coexistent intraplacental
