ABSTRACT
The purpose of this study were to evaluate the findings of gestational trophoblastic disease(GTD) at colorDoppler imaging (CDI) and to assess the role of CDI in differentiating gestational trophoblastic tumor (GTT) fromhydatidiform mole (H-mole). CDI findings of 18 patients with H-mole and 52 patients with GTT were reviewed. Masswas detected in 43(82,7%) patients with GTT. Thity seven out of 43 masses showed varying degree of intratumoralflows. mean resistive index (RI) of intratumoral flow was 0.39+0.15. H-mole manifestated as a characteristicvesicular mass in 6 patients without history of curretage, while there was no definable mass in 12 patients withhistory of curretage. The masses of H-mole did not show intratumoral flow. Hypervascularity of adnexae wasdetected in 44 (84.6%) patients with GTT, whereas only six (33.3%) patients with H-mole showed minimalhypervascularity of adnexae. Mean RI of uterine arteries was 0.69+0.13 in GTT and 0.70+0.15 in H-mole. CDIfindings of mass in the uterus, hypervascularity of adnexal region and intramural vessels in patients suspected tohave GTD clinically, may suggest GTT. In conclusion, CDI was helpful in the diagnosis of GTD and thedifferentiation between H-mole and GTT.
