目的探讨螺旋CT在气管支气管结核诊断中的作用。方法我院2007年1月至2009年1月收治的经手术病理和纤维支气管镜活检证实的气管支气管结核21例,对其临床资料进行回顾性分析。结果 21例中,18支病变支气管表现为支气管壁不同程度向心性增厚,管壁厚度约3～9mm,内壁呈浅波浪状。其中15支受累支气管范围较长,长度达30mm,占83.3%(15/18)。4支病变支气管壁出现钙化。21例均合并肺内结核。结论螺旋CT可以有效显示气管支气管结核的病变特征,CT对支气管结核的诊断具有重要价值。
Objective To explore the role of spiral CT in the diagnosis of tracheobronchial tuberculosis. Methods Twenty-one cases of tracheobronchial tuberculosis confirmed by pathology and fibrobronchial biopsy in our hospital from January 2007 to January 2009 were retrospectively analyzed. Results Among the 21 cases, bronchial lesions of 18 lesions showed concentric thickening to varying degrees on the bronchial wall, with a wall thickness of about 3 to 9 mm and a shallow wavy inner wall. Among them, 15 had a longer range of bronchial involvement, with a length of 30 mm, accounting for 83.3% (15/18). 4 lesions of bronchial calcification. 21 cases were complicated by pulmonary tuberculosis. Conclusion Spiral CT can effectively show the pathological features of bronchial tuberculosis. CT is of great value in the diagnosis of bronchial tuberculosis.
