Ultrasonic evaluation of trophoblastic disease and the response to chemotherapy.
Ultrasound is an established method of confirming the presence of a hydatidiform mole in utero. However, in agreement with other investigations, we have often noted that the appearance of this entity is less specific than originally reported. To elucidate this, the ultrasonic patterns of 26 patients with trophoblastic disease and 27 with other entities were reviewed. Since there is a paucity of literature with regard to the response of choriocarcinoma to chemotherapy, determined by ultrasound, we simultaneously studied the relationship between findings of the ultrasonograms and the levels of hCG-beta-subunit in sera. We noted variable ultrasonic features in trophoblastic disease, and the sonograms of the choriocarcinoma have occasionally been confused with those of hydatidiform mole. If special attention is directed to the thickness of the placenta-like echoes as well as the sonolucent areas within it, the diagnosis of partial hydatidiform mole may be feasible. We also noted a rough correlation between ultrasonic appearances and the hCG-beta-subunit value, determined during chemotherapy for choriocarcinoma.
