Succenturiate lobe of placenta with vessel anomaly: a case report of prenatal diagnosis and literature review.

We report the case of a 33-year-old woman with antenatal ultrasound diagnosis of succenturiate placental lobe at 33 weeks confirmed by B-flow rendering, describing the advantages of the application of color Doppler to diagnosis and management of placental anomalies. We searched studies about antenatal diagnosis of succenturiate placental lobe, including only cases in which color Doppler was used. This case underlines the importance of color Doppler in increasing the accuracy of diagnosis and achieving an improved differential diagnosis.
