目的:分析空洞性肺结核与空洞性肺癌的CT特征。方法:回顾分析经病理及临床证实的空洞型肺结核及空洞型肺癌,评价空洞壁及周围特点。结果:21例空洞性肺结核,其中薄壁17例,厚壁4例,偏心空洞6例,有壁结节4例,毛刺6例,卫星病灶12例,胸膜尾征4例,纵隔淋巴结肿大3例,病灶临近胸膜下脂肪线增厚4例;18例空洞性肺癌,厚壁16例,薄壁2例,其中15例为偏心性,有浅液平6例,呈分叶状13例,伴卫星灶2例,胸膜尾征12例,血管集束征11例,胸腔积液6例,淋巴结肿大12例。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 analyze the CT features of cavitary and hollow lung cancer. Methods: Retrospective analysis of pathological and clinically confirmed cavitary pulmonary tuberculosis and cavity type lung cancer, evaluation of the cavity wall and the surrounding characteristics. Results: 21 cases of pulmonary tuberculosis, including thin wall in 17 cases, 4 cases of thick wall, 6 cases of eccentric cavity, wall nodules in 4 cases, burr in 6 cases, 12 cases of satellite lesions, 4 cases of pleural symptoms, mediastinal lymph nodes 3 cases, lesions near the subpleural fat line thickening in 4 cases; 18 cases of empty lung cancer, thick wall in 16 cases, thin wall in 2 cases, of which 15 cases were eccentric, shallow liquid level in 6 cases, lobulated in 13 cases , With satellite lesions in 2 cases, pleural tail sign in 12 cases, vascular bundle sign in 11 cases, pleural effusion in 6 cases, 12 cases of lymphadenopathy. Conclusion: CT has more important value in distinguishing lung cancer cavity from tuberculosis cavity.
