Placental mesenchymal dysplasia (PMD) is a rare benign vascular anomaly of placenta, with an echographic pattern similar to a hydatidiform mole in the form of a placentomegaly with multiple cystic lesions. The case of diagnosed PMD in the second trimester with a normal pregnancy outcome is reported. The dynamics of the echographic pattern during pregnancy is presented, and the differential-diagnostic series and prognosis of pregnancy are discussed. When making a differential diagnosis of cystic changes in the placenta detected with ultrasound, the physisian should remember about a rare pathology as placental mesenchymal dysplasia, which featured the absence of high_speed signals of blood flow inside the affected area and a normally appearing fetus.

Key words: ultrasonography, Doppler ultrasound, placental mesenchymal dysplasia, differential diagnosis
