【摘要】 本文分析了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征像,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％。更多还原

【Abstract】 The CT 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 1 cm, mediastinal pleural involuement, and hilar of madiastinal adenopathy. 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 92.9%, 83. 3%, and sensitivity were 74%, 28.5% respectively.更多还原
