[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。
[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.
