肺结核、肺癌、肺炎的CT误诊分析及鉴别诊断(附28例报告)

CT Misdiagnosis and Differential Diagnosis of Pulmonary Tuberculosis, Cancer and Inflammation (A Report of 28 Cases)

目的:对28例肺部疾病(肺癌、肺结核、肺炎)CT误诊回顾分析,总结经验、教训,提高鉴诊认识。方法:28例患者均行CT扫描,其中21例被病理证实,其余的经临床随访证实。结果:肺癌与肺结核误诊10例。肺结核并发肺癌9例,肺结核误诊为肺炎6例,肺炎与肺癌误诊3例。结论:肺癌、肺结核、肺炎CT鉴别困难,要细致研究CT表现,综合分析,才能尽量减少误诊。

Objective: CT misdiagnosises of 28 patients with pulmonary diseases (pulmonary cancer, tuberculosis, inflammation) were analyzed retrospectively in order to sum up the experience or lesson and improve the knowledge of their differential diagnosis. Methods:All 28 cases were scanned by CT,among them,21 cases were confirmed by pathological examination and the rest by clinical practice. Results: There were 7 cases with pulmonary cancer and 3 cases with tuberculosis mistaken for each other and 3 cases misdi-agnosed as pulmonary cancer. 9 cases with pulmonary tuberculosis were complicated by pulmonary cancer. 6 cases with pulmonary tuberculosis were misdiagnosed by pulmonary inflammation. Conclusion: It is difficult to differentially diagnose pulmonary cancer, tuberculosis and inflammation. Probability of misdiagnosis can be reduced only by careful studying the CT features and synthetical analysing them.
