What does a molar pregnancy look like on ultrasound?
The presence of the molar tissue is then detected. Ultrasound scanning shows a honeycomb pattern produced by the numerous vesicles. As they enlarge the image is described to look like a snowstorm, which is due to swollen cysts with bleeding into the uterus. The ovaries are often seen to contain large cysts.

What happens if a molar pregnancy is not treated?
