目的 :探讨恶性胸腔积液的CT表现特点 ,及CT在恶性胸腔积液诊断中的应用价值。材料与方法 :分析 5 6例经手术、病理、胸水等证实的恶性胸腔积液的CT征象。结果 :恶性胸腔积液的特征性CT表现为胸膜的明显增厚。其形态改变有一定特点 ,可分为四型。但CT对无或仅有轻度胸膜增厚的恶性胸腔积液的诊断仍较困难。结论 :CT是诊断恶性胸腔积液的重要检查方法之一 ,可清楚显示胸膜增厚的范围及程度 ,后者是鉴别诊断中有重要价值的CT征象
Objective: To investigate the CT features of malignant pleural effusion and the value of CT in the diagnosis of malignant pleural effusion. Materials and Methods: CT findings of 56 malignant pleural effusions confirmed by surgery, pathology and pleural effusion were analyzed. Results: The characteristic CT findings of malignant pleural effusion were significant pleural thickening. The morphological changes have certain characteristics, can be divided into four types. However, the diagnosis of malignant pleural effusion with or without mild pleural thickening is still more difficult. Conclusion: CT is one of the important methods for the diagnosis of malignant pleural effusion. It can clearly show the range and extent of pleural thickening, which is a CT sign of great value in differential diagnosis
