摘要
目的探讨X线胸片误诊肺结核的原因及CT对肺结核的诊断价值。方法对X线胸片误诊而经临床确诊并具有完整临床、影像资料的肺结核病例89例进行X线胸片和CT对照回顾性分析。结果(1)X线胸片下肺叶病灶占44.9%,CT显示下叶基底段病灶最多,占32.0%。(2)胸部CT发现X线胸片漏检早期肺结核病灶11.8%、肺内隐匿部位病灶43.3%和早期粟粒性结核6例。(3)胸部CT对肺结核血行播散及支气管播散、支气管壁增厚、胸膜增厚及粘连、纵隔淋巴结肿大及钙化的显示率明显高于X线胸片。结论CT检查对肺结核诊断及鉴别诊断具有重要价值,建议在X线胸片诊断不明确时及时作CT检查。
Objective To determine the cause of X-ray misdiagnosed cases and the diagnostic value of CT in pulmonary tuberculosis. Methods A retrospective analysis was done through comparing the clinical information, X-ray film and CT film of 89 patients with pulmonary tuberculosis. Results The lesions showing finding in X-ray included prime tuberculosis （11. 8%）, intrapulmonary invisible location （43.3%）, and prime blood spread （n=6）, but were completely presented in chest CT films. The blood spread lesions, bronchogenic spread lesions, thickened wall of bronchus, pleural thickening, inner-mediastinum lymph node enlargement and calcification in chest CT films showed higher rate than that of X-films. Conclusion The value of chest CT for providing evidences for diagnosis and in differentiating diagnosis of TB is very importam. We suggest that we should do CT detection in time when X-films showed and no positive in diagnosis.
