This is a partial molar pregnancy.

Explanation

The image shows an enlarged uterus with a small irregular gestational sac. Non-viable embryo was reported seen (not documented in the image). The placenta is thick and hyperechoic with multiple small anechoic spaces and increased blood flow on color Doppler. The ultrasound findings are consistent with partial molar pregnancy.

 

Figure – Partial molar pregnancy. Observe the irregular gestational sac (arrows). If a gestational sac (GS), embryo or embryo/fetus parts are seen along with the molar pregnancy cystic lesions then it is a partial molar pregnancy.
