肺癌的X线、CT诊断与病理分析

Study about Histopathological Diagnosis of Lung Cancer by X-ray and CT

目的:研究肺癌的影像学和病理学表现的相关性。方法:对36例肺癌的X线、CT和病理特征进行分析。结果:6例见肺门高密度肿块,致支气管管腔狭窄伴亚段支气管粘液栓,与肺动脉伴行,CT增强扫描周边有强化;22例鳞癌向支气管管腔内生长引起支气管狭窄,早期见局限性肺气肿,中、晚期见19例阻塞性肺炎及肺不张(86.4%),12例纵隔窗显示淋巴结肿大;8例周围型小肿块,直径≤2cm,肿块边缘呈细短毛刺,边缘有明显的分叶,其中1例肿块内有不规则偏心性空洞。结论:肺癌的X线、CT、病理组织学三者密切结合,能够提高肺癌诊断的准确率。

Objective To study the co-relation of radiological and histopathological features of lung cancer. Methods X-ray CT and histopathological features of 36 cases of lung cancer were analyzed retrospectively. Results High-density mass with strengthened edge was found to be paralleled with lung atery at lung gate in 6 cases. As a result, bronchial tubes became narrow with mucus in it. Squamous carcinoma tissues of 22 cases were showed growing within bronchial tubes. Local lung emphysema in early stage obstructive pneumonia and 19 cases of lung collapse in mid/late stage（86.4%） were brought out because of narrow cavity of bronchi. Megaly lymph nodes were seen by mediastina window in 12 cases. Peripheral mass with leaf-like edge were found in 8 cases,and the diameter of each was less than 2cm,while irregular deviated cavitative was seen in one case. Conlusion It is suggested that close combination of X-ray CT and histopathological can improve the accurate rate of diagnosis in lung cancer.
