Succenturiate lobe of placenta

Case contributed by Alexandra Stanislavsky


Antenatal scan at 23 weeks

Patient Data

Age: 23 weeks gestation
Gender: Female

Evaluation of the placenta during a singleton second trimester ultrasound demonstrates the main body of the placenta positioned along the posterior uterine wall.  A separate placental lobe is seen anteriorly, with the connecting vessels extending across the fundus. 

Case Discussion

Appearance is consistent with a succenturiate placenta.

Importantly, greyscale and color images of the internal os are obtained to demonstrate that there is no vascular connection across the os (i.e. no vasa previa).
