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.
停经16周时，经阴道彩色血流成像诊断为异位妊娠中的侵袭性葡萄胎。彩色血流成像是用于核实诊断的唯一非侵入性方法。在此病例中，人绒毛膜促性腺激素（HCG）血清水平非常低（0.196 IU/ml），且无主观症状和子宫出血。
