摘要
目的对不同时期的周围型肺癌X线影像进行分析,以提高早期影像诊断水平。方法搜集有较完整X线随访资料的26例周围型肺癌,总结其早期征象。结果早期征象表现为肺内单发结状病灶,平均直径为15mm,中等密度;病灶内部构造:早期可见空泡征,进展期可见细小钙化病灶,空洞则多见于进展期;边缘情况:毛刺、分叶征、兔耳征及胸膜萎缩征等,进展期明显多于早期。结论直径15mm以内,边缘有毛刺、分叶征及胸膜萎陷征等,瘤内有空泡征,无论临床有无症状,均提示早期周围型肺癌。
Objective To study the X-ray imaging of peripheral lung cancer in diiterent penods and improve me level of early imaging diagnosis. Methods The follow-up data of 26 cases of peripheral lung cancer with X-ray of relatively complete were collected, and the early signs were mainly summarized. Results The performance of early signs was intrapulmonary single nodular lesions, the average diameter was 15 ram, with medium density; internal structure of lesions： vacuole sign was seen in the early stage, and tiny calcified focuses were seen in the progressive stage, and the cavitation was common seen in the progressive stage; the margin showed lobulation, spiculation, hare-ears sign and pleural indentation and so on, which of progressive stage were more than that of early stage. Conclusion That of diameter within 15mm, the margin with lobulation, spiculation, pleural indentation and so on, vacuole sign in tumor, with or without clinical symptoms, are all imply early peripheral lung cancer.
