A true accessory placental lobe: Two case reports of a novel morphological placental anomaly, distinct from succenturiate and bilobed placenta

Introduction: The placenta is a complex organ, originating from both fetal and maternal tissues. Morphological placental anomalies are rare but can result in significant morbidity and mortality for both the fetus and mother. The use of ultrasound imaging to detect these anomalies has led to improved outcomes; however, the use of ultrasound technology for non-medical purposes, such as “keepsake” imaging has proved more controversial.
