【摘要】 目的　分析薄壁空洞性和囊性肺癌的CT表现及其病理基础。方法　对 14例主要表现为薄壁空洞和 9例表现为完全或绝大部分囊变的肺癌病例的不典型CT表现进行分析 ,并与其病理表现进行对照分析。结果　该 2 3例具有不典型CT表现的肺癌均有其一定的病理基础。其中 10例CT表现为薄壁空洞和 5例CT表现为完全或绝大部分囊变的肺癌中 ,病理光镜下表现均可见有大片坏死区 ;4例薄壁空洞性和 3例完全囊变的肺癌病理光镜下表现可见大量癌细胞合并多处小片坏死区。结论　①肺癌瘤体内坏死液化是肺癌形成空洞或囊性改变等不典型CT表现的主要成因。②肺癌瘤体内大量间质纤维化并玻璃样变性是肺癌CT表现为囊性改变的另一成因。③不典型CT表现给鉴别诊断造成一定困难 ,尤其是薄壁空洞性肺癌。对于内壁不甚规则之薄壁空洞性病变 ,应警惕肺癌更多还原

【Abstract】 Objective To analyse the CT appearance of lung cancer which appeared cave with thin wall or cystoid and their foundation of pathology. Methods Analysed CT appearance of 14 lung cancer cases which appeared cave with thin wall and 9 cases which was being cystoid completely or mostly ,and compared to their foundation of pathology. Results These 23 lung cancer cases with untypical CT appearance had their definite foundation of pathology. There were 10 lung cancer cases which appeared cave with thin wall and 5 cases which was being cystoid completely or mostly,these all a great deal of putrescence all could be found on their pathology;many little putrescence in 4 lung cancer cases which appeared cave with thin wall and 3 cases which were cystoid completely; and multitudinous intersticial fibrosis and fibrous tissue hyperplasia and glass denaturalizati of fibrous tissue in 1 cases which was cystoid completely. Conclusion ①The main cause that lung cancer appeared cave with thin wall or cystoid is putrescence and liquefaction in tumours.②Another cause which lung cancer appeared cystoid is intersticial fibrosis and glass denaturalizati in tumors. ③Untypical CT appearance brought some difficulties on differencial diagnoses, especially the apearance of cave with thin wall. As the caves with thin wall which their interior wall are not regular, the lung cancer should be suspected.更多还原
