目的:探讨支气管内膜结核与中央型肺癌的螺旋CT表现,提高对支气管内膜结核与中央型肺癌的诊断水平。方法:回顾性分析经手术病理、纤支镜病检及痰检证实的48例中央型肺癌与66例支气管内膜结核的多排螺旋CT表现,总结各型病变的影像学特点。结果:48例中央型肺癌中能够显示支气管管壁增厚、管腔狭窄44例,阻塞性肺不张8例;66例支气管内膜结核中能够显示支气管管壁增厚62例,管腔狭窄后扩张36例,阻塞性肺不张16例。结论:支气管管壁增厚的厚度及长度、管腔狭窄后是否有扩张,对中央型肺癌与支气管内膜结核的诊断与鉴别诊断有重要价值。
Objective: To investigate the spiral CT findings of endobronchial tuberculosis and central lung cancer, and to improve the diagnosis of bronchial endometrial tuberculosis and central lung cancer. Methods: The CT findings of 48 cases of central lung cancer and 66 cases of endobronchial tuberculosis confirmed by operation and pathology, bronchoscopy and sputum examination were retrospectively analyzed. The imaging features of each type of lesions were summarized. Results: Bronchial wall thickening, luminal stenosis in 44 cases, obstructive atelectasis in 8 cases were found in 48 cases of central lung cancer. In 66 cases of bronchial endometrial tuberculosis, 62 cases of bronchial wall thickening, After the expansion of 36 cases, obstructive atelectasis in 16 cases. Conclusion: The thickness and length of bronchial wall thickening and whether there is expansion after stenosis have important value in the diagnosis and differential diagnosis of central lung cancer and endobronchial tuberculosis.
