目的:总结胸膜间皮瘤的CT表现特点。方法:经病理证实的11例胸膜间皮瘤均先行CT检查后发现,其中5例行开胸手术,4例行胸膜活检,2例行CT定位下穿刺。结果:11例胸膜间皮瘤中,4例为良性,7例为恶性。位于左侧胸腔7例,右侧胸腔4例;6例为局限型单发胸膜增厚或肿块,其中良性4例,恶性2例。5例为弥漫型,均为恶性。11例中合并胸水6例,1例伴有肺内转移,2例伴有肋骨或胸骨破坏及累及大血管。结论:CT能很好地显示病变部位、形态、大小、与邻近组织的关系,有无胸水及转移,有助于鉴别良、恶性肿瘤,为临床诊断提供有价值的诊断及治疗依据。
Objective: To summarize the CT features of pleural mesothelioma. Methods: 11 cases of pleural mesothelioma confirmed by pathology were examined by CT. Among them, 5 cases underwent thoracotomy, 4 underwent pleural biopsy, and 2 underwent CT puncture. Results: Of the 11 cases of pleural mesothelioma, 4 were benign and 7 were malignant. In the left chest in 7 cases, right chest in 4 cases; 6 cases of localized solitary pleural thickening or mass, of which 4 were benign and 2 were malignant. 5 cases were diffuse, are malignant. In 11 cases, there were 6 cases with pleural effusion, 1 case with pulmonary metastasis, 2 cases with rib or sternum destruction and involving large blood vessels. Conclusion: CT can display the location of the lesion, the shape, the size, the relationship with the adjacent tissue, the presence or absence of pleural effusion and the metastasis, which is helpful to distinguish benign and malignant tumors and provide valuable diagnosis and treatment basis for clinical diagnosis.
