摘要
目的研究小于2cm肺小结节内空洞影的CT诊断及意义。方法收集的39例肺结节(直径小于2cm),其中肺癌结节16例,其他良性结节23例。CT平扫及增强扫描。CT重点分析肺结节内空洞影的形态、大小及分布。比较各结节内空洞影出现的差异。T检验及x2检验统计分析相关数据。结果全部病例的肺小结节内均出现单逗点状和多点状小空洞影。良恶性结节内单点状与多点状小空洞影出现率相差均显著(P<0.05),良性结节内单点状小空洞影的出现较多,恶性结节内多点状小空洞影出现机率较多。结论肺小结节内空洞影形态和数目在良、恶性结节中出现率有显著差异,对病变的定性诊断有一定的意义。
Objctive To study the diagnostic significance of cavities in lung nodules with diameter less than 2cm with CT. Methods 39 pulmonary nodules（diameter≤2cm） were collected randomly. All cases were confirmed by operation or biopsy pathology. Of all the 39 pulmonary nodules. 16 were primary lung cancer, 23 were benign nodules, including tuberculosis, and organized pneumonia. All cases received CT non-contrast and contrast examination. The size, shape and site of small cavity in the nodules were analyzed and the difference of the occur rate of different small cavities in different kind of nodules were analized with t and x^2 test.Results All the cases appeared punctate and multi-punctate small cavities. The punctate lucency occured mostly in the benign nodules, while multi-punctate mostly in malignant nodules. There were statistical difference between them （P〈0.05）,Conclusion The number and shape of small cavity in the pulmonary nodules less than 2cm have diagnostic and differential diagnostic significance.
