弥漫性胸膜病变CT诊断评价（附120例分析）

CT IN THE DIAGNOSTIC EVALUATION OF DIFFUSE PLEURAL DISEASE(ANALYSIS OF 120 CASES)

本文分析１２０例弥漫性胸膜病变的ＣＴ征象，所有病例均经临床评估及病理证实，其中恶性胸膜病变８５例，良性病变３５例。作者认为：结节性胸膜增厚、胸膜瘤样增厚，胸膜不规则增厚厚度大于１ｃｍ及纵隔胸膜增厚受累，纵隔及肺门淋巴结受累为恶性胸膜病变较为特征性的ＣＴ征象，其特异性分别为１００％、１００％、８９％、６８％和９８．５％。敏感性分别为６８％、８．２％、７６．４％、３５．３％和８１％。胸膜线状粘连增厚和钙化多提示良性病变，其特异性分别为９２．９％和８３．３％。敏感性分别为７４％和２８．５％。

The CF features of 120 cases with diffuse pleural diseases were analysed (85 malignant and 35 benign).The results indicated that helpful features in distinguishing malignant from benign were nodular pleural thickening, tumor-like pleural thickening,irregular pleural thickening greater than 1cm, mediastinal pleural involvement, and hilar or mediastinal adenoliathy.The specificity of these findings were 100%,100%,77%,68%,98.5% and the sensitivity were 70. 6%, 8.2%, 77.6%, 35.3%,81% respectiviely.Pleural string shaped stick and calcification were more suggestive of a benign process.the specificity were 92.2%,83.3%,and sensitivity were 74%,28.5% respectively.
