周围型小肺癌的CT诊断(附33例报告)

摘要

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.%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.
