我们分析了经手术和病理证实的外周型肺癌１１７例的Ｘ线表现，见“核晕征”３５例（２２．９％）。４４例单发肺转移癌中见６例（１３．６％）。１６７例肺良性病灶及４例原发性肺肉瘤均无一例见到此征。１４例有核晕征肺癌的Ｘ线与病理对照结果表明１２例癌核心区的癌实质多于间质，另外２例两者相等。反之癌晕环区的癌实质少于间质。对核晕征的动态观察说明此症是癌生长过程中的一个阶段的表现。笔者认为核晕征对外周型肺癌尤以≤３ｃｍ小肺癌的早期诊断是一个非常重要的Ｘ线征象。
We analyzed the X-ray findings of 117 cases of peripheral lung cancer confirmed by surgery and pathology. See “Nuclear halo sign” in 35 cases (22.9%). In 44 cases of single lung metastases, 6 cases (13.6%) were seen. None of the 167 benign pulmonary lesions and 4 primary pulmonary sarcomas were seen. The X-ray and pathological comparisons of 14 cases of lung cancer with halo sign showed that the cancer core area of 12 cases was more than the mesenchyme, and the other two cases were equal. In contrast, the cancerous nature of the cancerous halo ring area is less than the mesenchyme. The dynamic observation of the nuclear halo sign indicates that this disease is a manifestation of a stage in the cancer growth process. I believe that the nuclear halo sign peripheral lung cancer, especially early diagnosis of lung cancer is less than or equal to 3cm is a very important X-ray signs.
