目的总结胸膜型肺癌的CT表现特征及其误诊原因,以提高诊断水平。方法回顾2010年1月-2013年12月经术后病理证实的8例胸膜型肺癌患者的CT资料,就病变部位、形态、大小、密度、增强特点、病变毗邻结构以及有无淋巴结肿大、胸腔积液等问题进行分析讨论。结果 8例胸膜型肺癌患者中,左侧6例,右侧2例;结节状3例,不规则肿块状5例;密度较均匀6例,病灶不规则稍低密度2例;邻近肋骨破坏4例;胸腔积液6例;纵隔淋巴结肿大5例,其中1例左肺门、左锁骨上区及左侧腋窝多发淋巴结转移;所有8例均为中度强化。结论胸膜型肺癌在CT增强检查中均有一定特征性表现,仔细分析其CT特征表现,并结合临床症状、胸水细胞学检查等资料可作出定性诊断,减少误诊。
Objective To summarize the CT features of pleural lung cancer and its causes of misdiagnosis in order to improve the diagnostic level. Methods CT data of 8 cases of pleural lung cancer confirmed by postoperative pathology from January 2010 to December 2013 were retrospectively analyzed. The location, shape, size, density, enhanced features, adjacent structures of the lesion and the presence or absence of lymphadenopathy, Effusion and other issues for analysis and discussion. Results In 8 cases of pleural lung cancer, there were 6 cases on the left and 2 cases on the right. There were 3 cases of nodules and 5 cases of irregular mass. The average density was 6 cases and the lesion was irregularly low density in 2 cases. 4 cases; pleural effusion in 6 cases; mediastinal lymph nodes in 5 cases, of which 1 case of left hilar, left supraclavicular and left axillary lymph node metastasis; all 8 cases were moderately enhanced. Conclusion Pleural - type lung cancer has certain characteristic manifestations in CT enhancement examination. The CT features of the pleural - type lung cancer are carefully analyzed. Combined with clinical symptoms and pleural fluid cytology, qualitative diagnosis can be made to reduce the misdiagnosis.
