摘　　要：目的探讨恶性胸膜间皮瘤（MPM）的CT表现及鉴别要点。方法回顾性分析经病理和（或）免疫组织化学证实的18例MPM的CT和临床资料。结果18例MPM的CT表现为：①17例表现为不同程度的胸膜增厚，胸膜增厚≥1cm者13例，另1例仅见大量胸腔积液；②弥漫型胸膜增厚13例，其中结节状增厚9例，环状增厚3例，肿块状增厚1例；③局限型胸膜增厚4例，其中肿块状增厚3例，结节状增厚1例；④病变同侧胸腔积液11例，纵隔固定而患侧胸腔体积缩小8例，肺内转移5例。结论MPM的CT表现有一定的相对特征性，结合临床资料和鉴别诊断，可以提高本病的诊断水平。Objective To discuss the CT features of malignant pleural mesothelioma（MPM） and the differentiated points. Methods CT findings and clinical datas of 18 cases with malignant pleural mesothelioma confirmed by pathology or immunohistochemistry were retrospectively analyzed. Results CT appearances of MPM included： ①17 cases were demonstrated various pleural thickening, and pleural thickness which was more than 1.0 cm was found in 13 cases,the another 1 case only to find large pleural effusion;②There were diffuse pleural thickening（n= 13 ）, included nodular pleural thickening （ n= 9 ）, annular pleural thickening （ n = 3 ）, and lumpy pleural thickening （ n= 1 ） ; ③There were localized pleural thickening （ n = 4 ）, included lumpy pleural thickening （ n = 3 ） and nodular pleural thickening （n= 1）; ④ 11 cases were found lesion ipsilateral pleural effusion,8 cases were found mediastinum immobi- lization and thoracic cavity narrowed,5 cases were found lung metastasis. Conclusion CT features of patients with malignant pleural mesothelioma were showed relative characteristic. In combination with clinical datas and differential diagnosis, the diagnosis of MPM can be improved.
