278例老年人涂阳肺结核X线平片表现

The chest X-ray findings of 278 cases of smear-positive pulmonary tuberculosis in old age

目的:探讨60岁以上老年人肺结核的影像表现特点,以提高诊断水平。方法:收集278例涂阳肺结核患者的普通胸片影像资料,年龄60～92岁,综合分析其临床及影像学特征。结果:病灶累及双侧肺168例,占60.43%,累及右肺下野161例,占57.91%,累及左肺下野者113例,占40.65%;其中以纤维化病灶为主要表现者169例,占60.79%;有空洞者107例,占38.49%;胸膜改变者156例,占56.12%。结论:老年肺结核在病灶的分布范围、部位上不同于青壮年,其病灶性质以空洞和广泛纤维化为特点,了解其临床及影像表现特征有利于肺结核的早期诊断和治疗。

Objective： To detect the imaging characteristics of smear-positive pulmonary tuberculosis in old people in order to improve diagnosis.Methods： 278 patients（age range：60-92） with confirmed pulmonary tuberculosis were analyzed in the clinic and imaging characteristics of radiological photograph.Results： Among 278 patients with pulmonary tuberculosis,the lesions were distributed bilateral lung in 168 cases（60.43%）.The lesions were found lower right lung in 161 cases（57.91%）.The lesions were found lower left lung in 113 cases（40.65%）.Fibrosis as the predominantly was seen in 169 cases（60.79%）.The cavity,pleural change were found in 38.49% and 56.12%,respectively.Conclusion： The main imaging characteristics of pulmonary tuberculosis in old age include diffuse fibrosis and cavity.The old age is different from other people in position and distribution range of lesion,which may help clinicians with early diagnosis and management of the Patients with pulmonary tuberculosis.
