The authors report the case of a round, peripheral radiographic opacity ("coin lesion" of English-language authors) which after surgical excision was found to be an intrapulmonary lymph node. In an anatomical study on the lymphatic drainage of pulmonary segments in adults, a similar lesion was found among 483 injected segments. A review of the literature yielded 27 similar cases which are described in detail. These lymph nodes are probably more frequent than is generally believed, as shown by an experimental radiolymphographic study. Such clinical findings will no doubt be rendered more numerous by the improved sensitivity of new medical imaging techniques. Despite hypotheses put forward by the authors, the presence of these lymph nodes, which seem to be acquired by the adult lung, has not yet been explained.
作者报告了一例圆形的外周放射影像学不透光区（英文文献作者称“硬币病灶”）病例，手术切除后发现是一个肺内淋巴结。在一项关于成人肺段淋巴引流的解剖学研究中，在483个注入的肺段中发现了类似病变。文献回顾得到了27例类似病例并进行了详细描述。一项实验性放射性淋巴造影研究表明，这些淋巴结可能比普遍认为的更为常见。新医学成像技术敏感性的提高无疑会使此类临床发现增多。尽管作者提出了一些假设，但这些似乎是成人肺后天形成的淋巴结的存在尚未得到解释。
