作者复习了已证实为妊娠滋养叶疾患的78名病人的 X 线胸片,提出在胸片中不仅应注意转移灶的性质,也应注意其量的变化。作者观察的78名绒癌和其它恶性滋养叶疾患的病人中35名有肺转移,其发生率为45%;并将肺转移分为以下三种类型。1. 典型转移:是最常见的类型,和大多数肺转移灶相同,是边界清楚的圆形阴影。 The authors reviewed the X-ray of 78 patients who had been proven to have nociceptive disorders of pregnancy and proposed that not only the nature of the metastases but also the amount of changes should be noted in the chest radiograph. Thirty-five of the 78 patients with choriocarcinoma and other malignant trophoblast diseases observed by the authors had lung metastases at a rate of 45%. The lung metastases were classified into the following three types. 1. Typical Metastases: The most common type, the same as most lung metastases, is a clear circular shadow on the border.
