- Heterogeneous focus along the anterior endometrium, adjacent to the inferior margin of the placenta, consistent with a succenturiate lobe. the hypoechoic areas within the succenturiate lobe are favoured to represent retroplacental haemorrhage given the clinical history.
- No vasa previa is demonstrated
- Remaining placenta is unremarkable
This case demonstrates ultrasound findings consistent with a succenturiate lobe of placenta (multilobed placenta), which confers and increased risk of vasa previa, placenta previa, antepartum haemorrhage, post partum haemorrhage and retained placenta (and therefore post partum infection).1
The succenturiate lobe was confirmed at the time of delivery, which was uncomplicated.
