摘　　要：目的：肺泡癌的Ｘ线表现多种多样，易误诊，为提高认识，探讨其Ｘ线特点。方法：收集两家医院１９７３－１０～１９９６－０２经病理证实的肺泡癌７４例，均有两次以上胸片，此外，ＣＴ４１例，分层２７例。结果：首次胸片误诊３８例（５１．４％），四周内复查或作ＣＴ后纠正诊断９例（１２％），根据影像表现分为五型：１．粟粒型；２．多发结节型；３．≤３ｃｍ单发结节型，４．３～５．７ｃｍ块状型；５．肺炎型。上述各型误诊由高到低依次为肺炎型、单发结节型、粟粒型、多发结节型。结论：各型Ｘ线表现有其特点，全面分析，及时复查，可望提高诊断正确率。Objective:To study the X-ray characteristics of alveolar cell carcinoma and improve the diagnostic accuracy.Methods:74 cases of alveolar cell carcinoma pathologically proved among two hospitals (Aug.1973-Feb.1996)were included.Every case had two or more times of lung films,CT scan was done in 41 cases and tomography in 27 cases.Results:38 cases were misdiagnosed on the initial films (51.4%),9 cases of them were corrceted by follow-up films or CT in 4 weeks(12%).Imagiologic features were classified into 5 types:1.miliary;2.multinodule;3.solitarynodule(≤3 cm),4.mass(3-5.7 cm);5.pneumonia-like.Misdiagnostic chances were listed from high to low:pneumonia-like、solitary nodule、miliary、multiondule.Conclusion:Eech type has its X-ray characteristics.The diagnostic accuracy can be improved by full analysis and follow-up films.
