THREE DIMENSIONAL SONOGRAPHIC IMAGING OF PLACENTAL MESENCHYMAL DYSPLASIA AND ITS DIFFERENTIAL DIAGNOSES

摘要

ObjectivePlacental mesenchymal dysplasia (PMD) is an uncommon vascular anomaly of the placenta characterized by mesenchymal stem villous hyperplasia. Its main sonographic features is a thickened placenta with hypoechoic areas, and an accurate sonographic diagnosis is challenging. The aim of this study was to report two cases of PMD, and discuss the differential diagnosis of its sonographic features.
