摘要:

［目的］探讨原发胸膜肿瘤的CT表现并评价CT的诊断价值。［方法］收集2001年至今行CT检查并经病理证实的胸膜原发肿瘤6例，对病变的形态学、范围、邻近结构的侵袭及增强模式分析。［结果］2例胸膜恶性间皮瘤，均见胸膜不规则增厚并伴同侧胸腔积液；2例良性孤立性胸膜纤维瘤，见边界光滑清楚肿物，推移邻近肺组织，增强见明显不均匀强化；1例恶性纤维组织细胞瘤，CT见边界光滑清楚肿物，推移邻近肺组织，增强见明显不均匀强化，并见侵袭肋间肌；1例纤维肉瘤，CT难以确定起源，仅见膈肌与心包间低密度不规则肿物，强化不明显。 ［结论］CT可清晰显示病变及其侵袭范围，帮助临床分期及评价肿瘤的可切除性。

Abstract:

［Objective］To explore CT feature and evaluate the value of CT in diagnosis of primary pleural tumor. ［Methods］Six cases primary pleural tumors which were conformed by pathology performed CT examnation. The morphologic features and contrast pattern were evaluated. ［Results］Two malignant mesotheliomas, CT appeared irregular and diffuse pleural thickness accompanied pleural effusion; 2 benign solitary fibrous pleural tumors were found large masses with smooth margin and inhomogeneous contrast; 1 malignant fibrous histocytoma also appeared smooth margin mass and inhomogeneous contrast accompanied invasion of intercostal muscle; 1 fibrous sarcoma appeared irregular mass without distinct margin and contrast. ［Conclusion］ CT play an important role in detection and evaluation of primary pleural tumor , and provide valuable information for clinical treatment.
