目的:分析3 cm以下周围型肺癌的CT表现及其鉴别诊断。方法:对40例直径小于3 cm的周围型肺癌患者进行回顾性分析。结果:40例小肺癌中,具有深分叶27例,细小毛刺18例,空泡征6例,空气支气管征3例,小空洞4例,胸膜凹陷征8例,血管集束征5例。26例进行了增强扫描,增强幅度在40~100 Hu之间。结论:对于3 cm以下周围型肺癌,全面分析病灶的边缘特征、内部结构以及周围组织的变化,可以提高诊断准确率。
Objective: To analyze the CT findings and differential diagnosis of peripheral lung cancer less than 3 cm. Methods: Forty patients with peripheral lung cancer less than 3 cm in diameter were retrospectively analyzed. Results: In 40 cases of small lung cancer, there were 27 cases with deep lobes, 18 cases with small burr, 6 cases with vacuolization, 3 cases with air bronchus, 4 cases with small cavity, 8 cases with pleural indentation and 5 cases with vascular bundle sign. Twenty-six cases underwent enhanced scan, with an increase of 40-100 Hu. Conclusion: For peripheral lung cancer less than 3 cm, the accuracy of diagnosis can be improved by comprehensively analyzing the characteristics of the margins, internal structure and surrounding tissues.
