Objectives: After studying the article entitled “Sonographic Evaluation of a Large Placental Chorangioma,” you will be able to:
Explain the symptoms and incidence of placental choriangiomas
Describe the role of sonography in fetal and maternal surveillance
Discuss therapeutic intervention for large placental choriangiomas
Chorioangiomas are benign tumors accounting for what percentage of pregnancies? 5% 1% 0.10% 0.50%
The least likely differential diagnosis for small placental chorioangiomas is: Harmartoma Venous Lake Gestational Trophoblastic Disease Capillary and villous stroma hyperplasia
Doppler assessment of which fetal vessel can demonstrate subtle signs of brain-sparing reflex from fetal blood shunting? Umbilical arteries Umbilical vein Middle cerebral artery Renal veins
In this case, a placental chorioangiomas was found in the which area? In the fundus of the uterus Near the cervix Near the maternal surface of the placental Near the fundal margin of the placenta
The differences in sonographic appearance of the placental chorioangioma from 19 weeks, 2 days (Figures 1 and 2) and 27 weeks 2 days (Figures 3 and 4) is that the placental lesion is: Roughly the same size lesion in both examinations Echogenic septa and excess fluids are demonstrated in Figures 1 and 3 Echogenic septa is demonstrated in Figure 3 with excess fluid Minimal vascularity is demonstrated in Figure 4
