不典型周围型肺腺癌CT误诊分析

Analysis of the atypical CT finging of peripheral pulmonary adenocarcinoma

目的探讨不典型周围型肺腺癌CT诊断。方法对19例病理证实均为肺腺癌进行回顾性分析,全部常规CT平扫及增强描,部分较小病变区行2.0mm薄扫。结果19例病变按CT征象不同分三型:肿块结节型7例,肺炎型6例,胸腔积液型6例。结论CT平扫及增强扫描对具有不典型CT征象的肺腺癌较难做出正确诊断。应仔细分析图像并重视病灶特征性征象,缺乏特征性影像病变的患者应密切结合病人诊疗病史,如病情顽固或反复者应警惕存在肺癌并应及早行肺穿刺细胞学检查或手术治疗。

[Objective] To summarize the manifestation and diagnosis of the atypical CT tinging of peripheral adenocarcinoma of lung on CT. [Methods] To perform the retrospective analysis in 19 cases of atypical peripheral adenocarcinoma of lung with CT images. All the cases had the CT plain scanning and the enhanced scanning. In the area of anomaly, some of the cases took the thin slice of 2 mm. [Results] Based on their CT findings, the carcinoma could be classified into 3 types： Masses or.nodules type 7 cases, pneumonic type 6 cases and plural effusion type 6 cases.[Conclusion] CT plain scanning and enhanced scanning are difficult to diagnose peripheral Pulmonary Adenoeareinoma with atypical CT tinging. We should analyse image carefully and pay more attention to characteristic changes in imaging.As to The patients who are lack of characteristic changes in imaging, we should combined closely with patients＇ history of therapy and prognosis, if the patient＇ s condition were repeated and obstinate, we should be on guard against lung cancer and perform the cellular examination of lung or the pneumonectomy as quickly as possible.
