""Partial Hydatidiform Mole "" is a type of molar pregnancy, which in turn falls under the spectrum of gestational trophoblastic disease.
On Ultrasound
🛑Greatly enlarged placenta relative to the size of the uterine cavity
🛑Cystic spaces within the placenta ("molar placenta"), which may not always be present
🛑An amniotic cavity (gestational sac), either empty or containing amorphous inappropriately small fetal echoes which may be surrounded by a relatively thick rim of placental echoes with intermingling cystic spaces
🛑Presence of a well-formed but growth-retarded fetus, either dead or alive with hydropic degeneration of fetal parts being frequently present
🛑Some partial moles can have sonographic appearances indistinguishable from those of the common complete moles or missed abortions 3, although an echogenic rim around the sac, as found in missed abortion or anembryonic pregnancy, is notably absent
🛑Colour Doppler interrogation may show high velocity and low impedance flow
