[Late complication of tubal pregnancy visualized with color Doppler ultrasound. A case report].

An invasive mole in an ectopic pregnancy was diagnosed in the 16th week post amenorrhoea by transvaginal colour flow mapping. Colour flow mapping was the only noninvasive method used to verify the diagnosis. In this case the serum level of human chorionic gonadotropin (HCG) was very low (0.196 IU/ml) and subjective symptoms and uterine bleeding were absent.
