肺结核性空洞与肺癌性空洞的CT表现和鉴别诊断

The CT manifestations and differential diagnosis of tuberculosis empty cavity and empty cavity of lung cancer

目的研究肺结核性空洞与肺癌性空洞的CT表现,评价CT对其鉴别诊断的价值。方法回顾分析经病理及临床证实的肺结核性空洞27例及肺癌性空洞29例,评价空洞壁及周围特点。结果癌性空洞一般为厚壁,内缘凹凸不平,有壁结节,分叶及胸膜凹陷征多见;而肺结核空洞以薄壁相对多见,周围常有卫星灶。厚壁空洞出现壁结节伴有胸膜凹陷征高度提示肺癌,而薄壁空洞,洞壁厚薄较均匀,周围伴有卫星灶者以肺结核最常见。结论 CT对鉴别肺癌性空洞和肺结核性空洞有较重要的价值。

Objective To study the CT manifestations of tuberculosis empty cavity and empty cavity of lung cancer,and evaluate the value of CT in differential diagnosis.Methods 27 cases of tuberculosis empty cavity and empty cavity of lung cancer confirmed by pathology and clinical were retrospective analyzed.Cavity wall and the surrounding features were evaluated.Results The empty cavity of lung cancer was generally thick-walled cavity,the inner edge uneven,there were mural nodule,leaf and more common pleural indentation;but tuberculosis was relatively common thin-wall cavity,satellite lesions surrounded.Lung cancer was suggested hole thick mural nodule associated with pleural indentation,while the thin-walled hollow,more uniform wall thickness,accompanied by satellite lesions around were most common the pulmonary tuberculosis.Conclusions The detection of CT had a more important value in differentiating tuberculosis empty cavity and empty cavity of lung cancer.
