胸膜CT特征对良、恶性胸腔积液鉴别的价值

The Value of CT Features of Pleural Change in Differential Diagnosis Between Benign and Malignant Pleural Effusion

目的探讨胸膜CT特征表现对良、恶性胸腔积液鉴别中的意义。方法回顾性分析我院2008年8月至2011年2月CT检查显示胸腔积液并胸膜改变的患者67例,其中恶性肿瘤患者42例,良性病变患者25例,对比观察2组患者的胸膜CT表现。结果恶性组胸膜弥漫线状增厚和胸膜钙化发生率低于良性组,差异有统计学意义(P<0.05);恶性组胸膜结节状增厚、不均匀环状增厚、条带状不规则增厚和纵隔胸膜受累发生率明显高于良性组,差异有统计学意义(P<0.05)。结论胸膜CT特征性改变对良、恶性胸腔积液鉴别诊断具有临床价值。

Objective To explore the value of CT features of pleural change in differential diagnosis between benign and malignant pleural effusion.Methods 67 patients with pleural change on CT were retrospectivly analyzed.Among them,42 cases with malignant pleural effusion and 25 with benign pleural effusion.CT features of pleural change were compared between the two groups.Results The incidences of widespreading thickening and pleural calcification on CT of the malignant group were significantly lower than those of the benign groups（P〈0.05）,while the incidence of tubercular thickening,uneven annular thickening,stripped irregular thickening,and involvement of mediastinum pleura were significantly higher than those of the benign groups（P〈0.05）.Conclusion Pleural change has great clinical significance in the CT diagnosis of benign and malignant pleural effusion.
