周围型小肺癌的CT诊断(附33例报告)

目的:探讨周围型小肺癌的CT表现,以提高CT诊断的准确性.方法:对33例经病理证实的周围型小肺癌CT表现作回顾性分析.结果:33例周围型小肺癌中腺癌19例,肺泡癌10例、鳞癌2例,小细胞肺癌1例,肺泡癌合并腺癌1例.病灶CT表现为边缘分叶征24例(72.7％),毛刺征15例(45.5％),空泡征10例(30.3％),空气支气管征9例(27.3 ％),磨玻璃征9例(27.3％),胸膜凹陷征8例(24.2％),血管聚集征5例(15.2％),瘤周气肿5例(15.2％),病灶内空洞5例(15.2％0).结论:]原发性周围型小肺癌螺旋CT征象有助于定性诊断.

The CT diagnosis of small peripheral lung cancer ( report of 33 cases)

Objective：To understand further the CT signs of smsll peripheral lung cancer and to improve its diagnostic rate by CT.Methods：CT findings of 33 cases of small peripheral lung cancer confirmed by pathology were retrospectively analyzed.Results：There were 19 cases of adenocarcinoma,10 cases of alveolar carcinoma,2 cases of squamous cell carcinoma,1 case of small cell lung cancer,1 case of alveolar carcinoma with adenocarcinoma in 33 cases of peripheral small lung cancer.Lesions on CT performance included edge leaf in 24 cases（72.7%）,burr sign in 15 cases（45.5%）,vacuole sign in 10 cases（30.3%）,air bronchogram sign in 9 cases（27.3%）,ground glass opacity in 9 cases（27.3%）,pleural indentation sign in 8 cases（24.2%）,vascular aggregation syndrome in 5 cases（15.2%）,peritumoral emphysema in 5 cases（15.2%）,within the lesion cavity in 5 cases（15.2%）.Conclusion：Primary small peripheral lung cancer spiral CT features contribute to the qualitative diagnosis.
