空洞见于9％的原发性肺癌,4％的转移性肺肿瘤。虽然肺部空洞性恶性肿瘤较少见,但有鉴别诊断意义。经 CT 检查共207例肺癌。96例原发性肺癌中,36例鳞癌,36例腺癌,19例小细胞癌,5例大细胞癌,皆经病理证实;111例转移性肿瘤,来自消化道者20例,泌尿生殖系22例,头颈部26例。结果:96例原发性肺癌中8例(8.3％)有空洞,腺癌最多,占13.9％,其次是鳞癌为8.3％,以未发现小细胞癌和大细胞癌空洞;111例转移性肺肿瘤中,5例(4.5％)有空洞,其中3例经病理证实。原发性肺癌年龄为58～73岁,平均68 Empty vision is found in 9% of primary lung cancers and 4% of metastatic lung tumors. Although cavitational malignancies in the lung are less common, they have differential diagnostic significance. A total of 207 lung cancers were examined by CT. Of the 96 primary lung cancers, 36 were squamous cell carcinomas, 36 were adenocarcinomas, 19 were small cell carcinomas, 5 were large cell carcinomas, and all were confirmed by pathology; 111 metastatic tumors, 20 from the digestive tract, urogenital Department of 22 cases, 26 cases of head and neck. RESULTS: Of the 96 primary lung cancers, 8 (8.3%) had cavities, and adenocarcinomas were the most common, accounting for 13.9%, followed by 8.3% of squamous cell carcinomas. No small cell and large cell carcinoma cavities were found; 111 cases were metastatic Among the lung tumors, 5 (4.5%) had holes, of which 3 were confirmed by pathology. Primary lung cancer is 58 to 73 years old, with an average of 68
