目的通过老年下肺结核误诊分析,减少老年肺结核患者的误诊。方法收集我院2000—2006年误诊的老年下肺结核患者45例,观察其临床表现,痰培养及支气管镜结果。结果误诊为慢性支气管合并感染25例,误诊为细菌性肺炎12例,误诊为支气管扩张合并感染8例。结论老年下肺结核患者,由于临床症状不典型、合并症多,故易误诊为肺部其它感染性疾病。 Objective To analyze the misdiagnosis of pulmonary tuberculosis in the elderly to reduce the misdiagnosis of elderly patients with pulmonary tuberculosis.

Results Misdiagnosed as chronic bronchial infection in 25 cases, misdiagnosed as bacterial pneumonia in 12 cases, misdiagnosed as bronchiectasis with infection in 8 cases.
