恶性胸膜间皮瘤的CT诊断

Diagnosis of malignant pleural mesothelioma by CT

目的:提高恶性胸膜间皮瘤CT诊断水平。材料与方法:回顾分析8例经病理证实恶性胸膜间皮瘤的CT表现。结果:(1)单侧胸腔大量积液并广泛胸膜增厚和胸膜结节2例;(2)胸膜肿块6例;(3)邻近软组织和器官侵犯8例。结论:CT检查发现广泛胸膜增厚、胸膜结节或肿块,伴邻近软组织和器官侵犯,提示恶性胸膜疾病。肿块穿过膈脚向上腹部或腹膜后延伸可视为恶性胸膜间皮瘤较具特征性的表现。

Objectives: To improve the CT diagnostic accuracy of malignant pleura! mesothelioma (MPM). Materials and Methods: CT findings of 8 cases of MPM proved by pathology were analysed retrospectiveg. Results: The main signs of CT included:(1) Unilateral many pleural effusion associate with diffuse irregular pleural thickening and pleural nodules in 2: (2) Pleural mass in 6. (3) The adjacent organs involved in 8. Conclusions: CT showing diffuse irregular pleural thickening and pleural nodules or mass, with adjacent organs involved, indicate malignant pleural diseases. Mass via the diaphragmatic crura derect extent into upper abdomen or retroperitoneum, which v:as more characteristic CT finding of MPM.
