本文分析了260例肺小细胞癌临床X线表现,通常分为3种亚型:(1)肺门纵隔型(62％),为最常见的典型表现对称或一侧性肺门纵隔增大及肿块,(2)气道阻塞型(23％),肺门及纵隔变化轻而缺乏肿块,以肺炎或肺不张表现明显。(3)周边肿块型(15％),X线显示肺内结节或肿块,并且肺门纵隔早期转移。本组有10例为特殊表现类似纵隔肿瘤极易误诊,建议为第4亚型即纵隔肿瘤型。另外CT检查在显示支气管继发阻塞性改变方面优于常规X线检查,故对诊断有困难时推荐CT检查是有益的。
This article analyzed the clinical X-ray findings of 260 cases of small cell lung cancer, usually divided into 3 subtypes: (1) hilar mediastinal type (62%), which is the most common typical symmetrical symmetry or lateral hilar mediastinal enlargement. And lumps, (2) airway obstruction (23%), hilar and mediastinal changes are light and lack of mass, with pneumonia or atelectasis. (3) Peripheral mass (15%), X-ray showed nodules or masses in the lung, and early metastasis of the hilar mediastinum. Ten patients in this group were particularly misdiagnosed with similarly-developed mediastinal tumors, suggesting that the fourth subtype is a mediastinal tumor type. In addition, CT examination is superior to conventional X-ray examination in displaying obstructive changes in bronchial obstruction. Therefore, it is useful to recommend CT examination for difficult diagnosis.
