慢性阻塞性肺疾病合并肺结核的影像表现

目的探讨COPD合并肺结核的影像表现。方法选自在我院就诊的COPD患者263例,143例COPD合并肺结核患者分为A组,120例COPD伴肺部感染患者为B组,对两组患者病变部位及范围、病变性质特点进行分析。结果两组比较中,病变范围,病变部位累及前部,病变性质的结节状病灶、斑片状纤维化、片状渗出性病灶P0.05;累及上叶尖后段和下叶背段,累及下叶基底段,病变性质的钙化灶、膈面粘连、多形态病灶混合、伴积液改变,差异具有统计学意义(P0.05)。结论 COPD合并肺结核影像表现为病变范围广泛,呈多肺叶散开模式,不典型部位经常被累及,多性状病灶混合存在,病变影像改变缓慢。

Imaging manifestations of chronic obstructive pulmonary disease complicated with pulmonary tuberculosis

Objective To explore the imaging manifestations of chronic obstructive pulmonary disease com-plicated with pulmonary tuberculosis. Methods 143 cases of chronic obstructive pulmonary disease complicated with pulmonary tuberculosis were divided into the group A, and another 120 cases of chronic obstructive pulmonary disease complicated with pulmonary infection were taken as the group B. The lesions′location and range and the nature of le-sions were analyzed. Results There was no significant difference in lesions nodules, patchy fibrosis, and flaky exu-dative lesions （P〉0. 05）. But there were obvious differences in upper lobe segment and dorsal segment of lower lobe basal segment involvement, leaves, lesions of calcification, diaphragmatic surface adhesion, multi form lesions mixed, with effusion change （P〈0. 05）. Conclusion The imaging features of patients with chronic obstructive pul-monary disease complicated with pulmonary tuberculosis show a wide range of lesions, with multiple lobe spread mode and atypical sites involved. There are many traits mixed and they change slowly.
