目的分析肺炎误诊为肺结核的CT特征,增强对肺炎、肺结核的认识,提高诊断水平。方法对我院2010年—2013年间CT初诊考虑为肺结核,后经临床实验室检查,消炎治疗后复查CT诊断为肺炎的32例患者进行分析。结果肺炎CT表现为大片状、小片状阴影,密度相对均匀,病灶内可见空气支气管征,边缘模糊不清。肺结核CT为多位于上叶尖后段或下叶背段的斑片影、结节影,病灶密度不均匀,可有空洞形成。结论由于抗生素的广泛应用或不恰当应用、环境污染、气候变化等因素的影响,肺炎的CT表现呈多样化,有时不易与肺结核区别,应结合病史、临床表现、实验室检查等综合分析,以便早期确诊和治疗。
Objective To analyze the CT features of pneumonia misdiagnosed as pulmonary tuberculosis, enhance the understanding of pneumonia and pulmonary tuberculosis and improve the diagnostic level. Methods Totally 32 newly diagnosed cases of pulmonary tuberculosis in our hospital from 2010 to 2013 were retrospectively analyzed by clinical laboratory tests and post-anti-inflammatory therapy. Results of pneumonia showed massive lamellar CT, small shadows, the density is relatively uniform, the air can be seen within the air bronchogram, the edge blurred. Pulmonary tuberculosis CT is located in the posterior segment of the upper or lower lobes of the patchy shadow, nodules, lesions uneven density, there may be empty formation. Conclusion Due to the wide application of antibiotics or improper application, environmental pollution and climate change, CT manifestations of pneumonia are diversified and sometimes difficult to distinguish from tuberculosis. Combined with history, clinical manifestations, laboratory tests and other comprehensive analysis, Early diagnosis and treatment.
