摘要
目的：讨论分析胸膜凹陷征形成的因素。方法：本组搜集了１９９１ 年１１ 月～１９９７ 年１１ 月间周围性肺癌１０５ 例，男７８ 例，女２７ 例。年龄２４～８０ 岁，平均年龄５９ 岁。其中鳞癌４１ 例，腺癌３８例，小细胞肺癌（ＳＣＬＣ）２３ 例，肺泡癌３ 例。通过统计学方法对此组肺癌的ＣＴ表现进行分析。结果与结论：胸膜凹陷征与肿块到胸壁的距离有关，距离越近，越易发生胸膜凹陷征；胸膜凹陷征与肿瘤远端是否有肺不张有关，有肺不张的肿瘤易产生胸膜凹陷征；胸膜凹陷征与肺癌的组织类型无关；胸膜凹陷征与肿块的大小无关；胸膜凹陷征与患者的性别及年龄无关。周围型肺癌远端的肺不张是其产生胸膜凹陷征的内在动力之一。
Objective: To discuss and analyze the factors related to the formation of pleural indentation sign(PIS). Methods: 105 Cases of peripheral lung cancer were collected from Nov 1991 to Nov 1997. 78 Cases were males and 27 cases were famales. Their ages ranged from 24 to 80 years, with an average of 59 years. 41 Cases had squamous cell carcinoma, 38 cases adenocarcinoma, 23 cases SCLC and 3 cases alveolar cell carcinoma. CT of these 105 cases were analyzed by statistical methods. Results and Conclusion: PIS has relation to the distance from tumor to thoracic wall, shorter the distance, higher the incidence of pleural indentation; PIS often has relation to patchy shadow at the distal end of tumor; there is no relation between PIS and histological types of lung cancer, size of tumor, sex and age of patient. Atelectasis at the distal end of peripheral lung cancer is one of the internal motive power in PIS formation, and the main external factor is the distance from tumor edge to thoracic wall.
