空洞型肺癌的CT诊断

目的　提高对空洞型肺癌CT表现的认识及诊断。方法　收集 1996-0 5～ 2 0 0 0 -0 6经CT引导下穿刺活检等病理证实肺癌 2 71例 ,其中发现空洞型肺癌 3 7例 ,占 13 .7%。结果　CT表现为厚壁空洞型 15例 ,圆形或类圆形空洞型 14例 ,实变肺内空洞型4例 ,薄壁囊肿空洞型 2例和裂隙状空洞型 2例等 5种类型 ,包括鳞癌 2 4例、腺癌 5例、小细胞癌 2例、大细胞癌 2例、腺鳞癌 2例和肺泡癌 2例。结论　空洞型肺癌中鳞癌多见 ,空洞型肺癌易误诊为结核 ,保守治疗无效者 ,早期穿刺活检有重要诊断价值

CT Diagnosis of the Cavitating Lung Cancer

Objective To improve the recognization of the cavitating lung cancer in CT scans.Methods From May 1996 to June 2000,37 patients out of total 271 primary lung cancers were confirmed by transthoracic needle aspiration biopsy,operation and pathlogical examination.Results There were 5 pattens cavitaties in the CT manifestations.They were 15 cases cavities with thick irregular walls,14 cases round or ovoid growths with central or eccentric cavitation,4 cases solid lobes containing cavities,2 cases thin-walled cavities resembling cysts and 2 cases fissural cavities.There were 24 cases squamous-cell carcinomas,5 cases adenocarcinomas,2 cases small-cell carcinomas,2 cases alveolar-cell carcinomas.Conclusion The cavitating lung cancer is made misdiagnosis easilier.There is important clinical value in diagnosis with transthoracic needle aspiration biopsy(TNAB).
