随着肺部诊断技术的普及,X线诊断、痰细菌学检查已广泛应用,90%以上的肺结核病均可以得到及时的诊疗。但由于某些临床症状及X线的不典型,痰检技术不熟练,以及肺结核病发病年龄向老年推移等种种因素,致使少数肺结核病例仍不能及时诊断,以致造成临床上的误诊。例如血行播散型肺结核可以误诊为伤寒;巨大孤立性空洞误诊为肺化脓;40岁以上成人肺门淋巴结核误诊为肺癌;下叶肺结核误诊为支气管肺炎、支气管扩张;干酪性肺炎
With the popularization of pulmonary diagnostic techniques, X-ray diagnosis and sputum bacteriological examination have been widely used, and more than 90% of tuberculosis can be diagnosed and treated promptly. However, due to some clinical symptoms and X-ray atypical, unsanitary sputum examination techniques, and the age of onset of tuberculosis to the elderly and other factors, resulting in a small number of cases of pulmonary tuberculosis is still not diagnosed in time, resulting in clinical misdiagnosis. Such as hematogenous disseminated pulmonary tuberculosis can be misdiagnosed as typhoid fever; huge isolated empty misdiagnosed as pulmonary suppuration; hilar lymphatic tuberculosis misdiagnosed as lung cancer in adults over the age of 40; lower lung tuberculosis misdiagnosed as bronchial pneumonia, bronchiectasis; caseous pneumonia
