title: Use of sonar in diagnosis and management of invasive gestational trophoblastic tumors.
abstract: Use of sonar in differential diagnosis between normal and molar pregnancies is well established. In this study, invasive trophoblastic tumors were investigated. Intrauterine masses were demonstrated sonographically in all 4 cases, As well as H.C.G. assay and chest X-ray, sonographic follow-up also seems to be of value in evaluating the effectiveness of the chemotherapy.
