Eighty-six cases of small peripheral lung cancer without contact with the chest wall on computed tomography (CT) scans were studied on the presence of radiological pleural indentation and pathological pleural invasion. Twenty-three tumors in 44 cases with pleural indentation were found to reach the pleura histologically, but only one in 42 cases without pleural indentation. There is a high possibility of pleural invasion or contact with the pleura in small lung cancers with pleural indentation. There was no relationship between the presence of pleural indentation and the tumor/chest wall distance on CT scans. Pleural indentations were more frequently seen in small adenocarcinomas of low ground-glass opacity (GGO) ratio or Noguchi's type C. Small lung nodules with pleural indentation had better be removed as early as possible because of the possibility of pleural invasion and pleural dissemination.
对86例在计算机断层扫描（CT）上未与胸壁接触的周围型小肺癌病例进行了研究，以观察放射性胸膜凹陷和病理性胸膜侵犯的情况。在44例有胸膜凹陷的病例中，23个肿瘤经组织学检查发现已累及胸膜，但在42例无胸膜凹陷的病例中只有1个肿瘤累及胸膜。有胸膜凹陷的小肺癌发生胸膜侵犯或与胸膜接触的可能性很高。胸膜凹陷的存在与CT扫描上肿瘤与胸壁的距离之间没有关系。胸膜凹陷在低磨玻璃密度（GGO）比率的小腺癌或野口C型中更常见。由于存在胸膜侵犯和胸膜播散的可能性，有胸膜凹陷的小肺结节最好尽早切除。
