摘　　要：目的了解CT对孤立肺结节的诊断意义.方法回顾性分析111例孤立肺结节,分析其CT征象.结果男83例,女28例,年龄27～87岁,平均59岁.111例中肺癌80例(鳞癌25例,腺癌42例,小细胞未分化癌5例,大细胞未分化癌1例,肺泡细胞癌7例),直肠腺癌肺转移1例.病灶直径1.5～4 cm,平均(3.10±0.77)cm;良性病变共30例,其中肺结核8例,错构瘤6例,隐球菌感染2例,炎性假瘤6例,慢性非特异性炎症4例,炎性肉芽肿2例,脓肿1例,球形肺不张1例;病灶直径0.8～4 cm,平均(2.47±0.94)cm.结论 CT是孤立肺结节诊断和鉴别诊断的首选方法.Objective To study the diagnostic value of CT in solitary pulmonary nodules. Methods CT characteristics of 111 cases of solitary pulmonary nodules were retrospectively analyzed. Results In the 111 cases, there were 80 cases of lung cancer (25 cases of squamous cell carcinoma, 42 cases of adenocarcinoma, 5 cases of small cell undefferentiated carcinoma, 1 case of large cell undefferentiated carcinoma, 7 cases of alveolar cell carcinoma) and 1 case of lung metastasis of rectal adenocarcinoma. The diameter of lesions was 1.5-4 cm with an average of (3.10±0.77) cm. In the 30 cases of benign lesions, there were 8 cases of tuberculosis, 6 cases of hamartoma, 2 cases of mycosis, 6 cases of inflammatory pseudotumor, 4 cases of chronic nonspecific inflammation, 2 cases of inflammation granuloma, 1 case of abscess, and 1 case of globular atelectasis. The diameter of lesions ranged from 0.8 cm to 4 cm with an average of (2.47±0.94) cm. Conclusion CT is the first choice in the diagnosis and differential diagnosis of solitary pulmonary nodule.
