ABSTRACT
Hydatidiform mole can be divided into complete (where there is no fetus) and partial/incomplete (where a fetus is present). Ultrasound shows the placenta to be an enlarged complex intrauterine mass containing many small cysts which can be described as grape-like (hydatidiform). The classic image of a snowstorm pattern can sometimes be seen, but the description is based on older ultrasound technology.
