Abstract: Aim: was to investigate characteristics of ultrasound image of hydatidiform mole (HM). Materials and methods: analyzed 15 cases of this type of gestational trophoblastic tumor, which was confirmed morphologically. Transvaginal ultrasound examination was carried out in the B-mode, using the technique of color and power Doppler. Results: it was marked out 2 ultrasound types of the tumor node in case of HM: cellular and solid-cystic. We have seen that the structure depends on the nature of the tumor vasculature. Conclusion: determination of nodes localization and vascular lacunae in it allows to identify the danger of massive bleeding. References 1. Genest D.R., Berkowitz R.S., Fisher R.A. et al.
