目的了解易误诊的肺结核病X线表现,以提高肺结核病确诊率和降低误诊率。方法对4533例肺结核病患者影像学资料进行分析。结果对肺内显示直径3cm以上的球形病灶的肺结核病易误诊为肺癌,误诊率为0.22%;对一侧中肺或下肺的孤立结核性空洞易误诊为肺囊肿或肺脓疡,误诊率为0.42%;对双中下肺多发斑片状阴影的病灶易误诊为小叶肺炎,误诊率0.55%。结论结核病X线表现形式多样,应综合多方面考虑,以降低误诊率。
Objective To understand the X-ray findings of easily misdiagnosed pulmonary tuberculosis in order to improve the diagnosis rate of pulmonary tuberculosis and reduce the misdiagnosis rate. Methods The imaging data of 4533 patients with pulmonary tuberculosis were analyzed. Results Pulmonary tuberculosis was more likely to be misdiagnosed as lung cancer in the lung than those with a diameter of 3 cm or more. The misdiagnosis rate was 0.22%. The isolated tuberculous villi in the middle or lower lung of the lung were easily misdiagnosed as pulmonary cysts or lung abscesses. The misdiagnosis rate Was 0.42%. The lesions of multiple middle and lower lungs with multiple patchy shadows were misdiagnosed as lobular pneumonia, with a misdiagnosis rate of 0.55%. Conclusion The manifestations of tuberculosis are various and should be considered in many aspects to reduce the rate of misdiagnosis.
