目的研究周围型肺癌空洞与肺结核空洞的CT表现。方法收集经病理与临床证实空洞形成的肺癌31例,肺结核空洞20例,分析评价空洞壁的厚薄、有无壁结节、液平,是否偏心分布,及病灶本身的特点,包括分叶、毛刺、钙化、周围卫星灶、胸膜凹陷征等情况。结果癌性空洞一般为厚壁,有壁结节,分叶及周围胸膜凹陷征多见,而结核空洞薄壁相对多见,常有卫星灶。结论厚壁空洞出现壁结节伴胸膜凹陷征高度提示肺癌。
Objective To study the CT findings of perivascular lung pits and tuberculosis cavities. Methods Thirty-one cases of lung cancer and 20 cases of pulmonary tuberculosis were collected by pathology and clinically confirmed emphysema. The thickness of the wall, the presence or absence of wall nodules, the level of fluid, the eccentric distribution and the characteristics of the lesion itself were analyzed, including lobulation and burr , Calcification, surrounding satellite stoves, pleural indentation and other conditions. Results The cancerous cavity is generally thick, with nodules, lobes and signs of pleural indentation more common, while the thin wall of tuberculosis is relatively common, often with satellite lesions. Conclusions The appearance of wall nodules with pleural indentation in the thick-walled cavity suggests lung cancer.
