四种弥漫性胸膜疾病CT影像特征

CT Features of Four Diffuse Pleural Diseases(Analysis of 63 Cases)

本文分析了恶性胸膜间皮瘤、胸膜转移瘤、脓胸、纤维胸等四种胸膜弥漫性疾病(共63例,其中恶性病变39例,良性病变24例)的CT 特征。结节性增厚、壁层胸膜厚度大于1cm 及纵隔胸膜受累、肺门和纵隔淋巴结受累多见于恶性病变,其特异性分别为96%、87%、79%和100%。敏感性分别为62%、33%、38%和33%。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%和100%,敏感性均为46%。

CT features of four diffuse pleural diseases were analysed,they included:63 cases ofmesothelioma,metastatic disease,empyema and fibro-thorax(39 malignant and 24 benign).The resultsshowed that features helpful in distinguishing malignant from benign were nodular pleural thickening,parietal pleural thickening greater than 1 cm,with mediastnal pleural involve-ment,and hilar ormediastinal adenopathy.The specificities of these findings were 96%,87%,79%,100% and thesensitivities were 62%,33%,38%,33% repectively.Pleural string shape stick and calcification weremore suggests a benign process,the specificities were 92%,100%,and the sensitivities were 46%evenly.
