目的:分析肺下叶结核X线误诊原因,提高对本病的诊断能力。方法:通过对经证实的45例肺下叶结核患者的X线表现及相关临床症状、体征进行分析,总结其X线表现特点及诊断要点。结果:肺下叶结核的X线表现有一定的特点,病灶形态多样(新旧病灶共存),本组病例初诊误诊率达62.22%(28/45)。结论:肺下叶结核易发生误诊,但掌握肺下叶结核的X线表现和临床特点,重视X线表现、临床表现及实验室检查的结合,是减少或避免误诊的关键。
OBJECTIVE: To analyze the causes of misdiagnosis of pulmonary X-ray in lower lung and to improve the diagnosis of this disease. Methods: X-ray findings and related clinical symptoms and signs of 45 confirmed pulmonary tuberculosis patients were analyzed. The X-ray findings and diagnosis points were summarized. Results: X-ray findings of pulmonary tuberculosis had certain characteristics. The morphology of the lesions varied with the coexistence of new and old lesions. The misdiagnosis rate of this group was 62.22% (28/45). Conclusion: Pulmonary tuberculosis is prone to be misdiagnosed. However, the key to reduce or avoid misdiagnosis is to master the X - ray findings and clinical features of pulmonary lobes and attach importance to the combination of X - ray findings, clinical manifestations and laboratory tests.
