周围型肺癌43例CT影像学特点分析

CT features of peripheral lung cancer：analysis of 43 cases

目的 总结周围型肺癌的CT影像学特点,提高对周围型肺癌的认识.方法 收集经病理证实的周围型肺癌43例,查阅文献及结合病理生理基础分析周围型肺癌CT征象,归纳总结其特点.结果 病例均经病理及临床证实,其中含空泡征2例,空洞型肺癌3例,分叶征39例（深分叶29例）,毛刺征41例,胸膜牵拉征37例,周围血管纠集征32例.结论 空泡征、癌性空洞、分叶征、毛刺征、胸膜牵拉征、周围血管纠集征等肿瘤的内部征象、边缘征象及周围征象反映了周围型肺癌的病理生理特点,对周围型肺癌的诊断具有重要意义.

Objective To summarize the CT imaging features of peripheral lung cancer,and im-prove the understanding of peripheral lung cancer. Methods Forty-three cases of peripheral lung cancer confirmed by pathology were collected,CT features of peripheral lung cancer were analyzed by literature review and pathological basis,and the characteristics were summarized. Results All cases were con-firmed by pathology and clinic,including 2 cases of vacuoles sign,3 cases of cavitation lung cancer,39 cases of lobulation （29 cases of deep lobulation）,41 cases of spiculation ,37 cases of pleural indenta-tion,32 cases of peripheral vascular convergence sign. Conclusions Internal signs,edge signs of tumour such as and peripheral signs vacuole sign,cancerous cavity,lobulation,pleural retraction,spicu-lation,peripheral vascular convergence sign react the pathophysiological features of peripheral lung canc-er,and they have important significance for the diagnosis of peripheral lung cancer.
