摘　　要：目的分析空洞性肺癌的CT表现及病理基础,以提高诊断水平。材料和方法回顾性分析经病理证实46例空洞性肺癌的CT表现,并与病理结果对照。结果46例中,鳞癌30例(65.2%)、腺癌8例(17.4%)、大细胞癌4例(8.7%)、小细胞癌3例(6.5%)和混合性癌1例(2.2%)。CT表现(1)肿块边缘具有恶性肿瘤的征象(毛刺征n=29,63.0%;分叶征n=26,56.5%;胸膜凹陷征n=25,54.3%;远侧阻塞性改变n=35,76.1%);(2)多为厚壁空洞(≥5mm38例,82.6%);(3)空洞壁厚薄不均(32例,69.6%);(4)空洞大(>3cm23例,50.0%);(5)多有壁结节(36例,78.3%);(6)空洞多偏心(25例,54.3%)。结论空洞性肺癌易发生于鳞癌,给合CT特征性表现对大多数患者可作出正确诊断。Purpose： To analysis the CT manifestations and pathological base of the pulmonary cavity carcinomas and to improve the diagnosis of the pulmonary cavity carcinomas on CT scans. Materials and Methods： The CT features of 46 cases with pulmonary cavity carcinoma proved by pathology were retrospectively analyzed, and compared with pathology. Results： Among 46 lesions there were 30 squamous cell carcinomas （65.2%）, 8 adenocarcinomas（17.4% ）, 4 large cell carcinomas（8.7% ）, 3 small cell carcinomas（6.5 % ）, and 1 mixed carcinoma（2.2% ）. The most common appearances of the pulmonary cavity carcinomas included ： （ 1 ） mass margin with signs of malignant tumour, such as spiculated sign（ n = 29,63.0% ）, lobulated sign（ n = 26, 56.5 % ）, pleural indentation sign（ n = 25, 54.3 % ）, distal side obstructive change （ n = 35, 76.1% ） ; （2） thick wall Cavity（ ≥〉5mm, n = 38, 82.6% ） ; （3）nonuniform and irregular cavity wall thickness （ n = 32, 69.6% ） ; （4） large cavity（ 〉 3cm, n = 23, 50.0% ） ; （5） mural nodule（ n = 36, 78.3% ） ; （6） eccentric cavity（ n = 25, 54.3 % ）. Conclusion ： The pulmonary cavity carcinomas more commonly occur in squamous cell carcinoma. With their characteristic CT appearances can be diagnosed conectly in the most cases.
