摘要
目的探讨合并糖尿病的老年肺结核患者CT征象特点,为临床诊断提供依据。方法 78例临床确诊的肺结核患者依据是否合并糖尿病分为糖尿病合并肺结核组(例数=39例)和单纯肺结核组(例数=39例),所有患者均完成双肺CT检查,比较分析两组患者的病变范围、病灶形态、以及斑片状大片状融合、多发空洞、多发树芽状支气管播散灶等特征性病变发生情况。结果糖尿病合并肺结核组病变范围累及双肺的发生率为84.62%,显著高于单纯肺结核组的61.54%,差异具有统计学意义(χ2=5.278,P=0.022)。与单纯肺结核组患者比较,糖尿病合并肺结核组患者病变范围累及两叶及两叶以上的发生率显著升高,为76.92%vs.53.85%,χ2=4.588,P=0.032。在病灶形态的比较中,糖尿病合并肺结核组患者渗出病变比例高而结节病变比例低,与单纯肺结核组患者比较,具有显著性差异,分别为43.59%vs.20.51%,χ2=4.768,P=0.029和76.92%vs.53.85%,χ2=4.522,P=0.033。对特征性的CT表现分析结果显示,糖尿病合并肺结核组患者CT表现为斑片状大片状融合的比例显著高于单纯肺结核组患者,为53.85%vs 28.21%,χ2=5.299,P=0.021;与单纯肺结核组比较,糖尿病合并肺结核组患者CT下多发空洞形成和多发树芽状支气管播散灶比例较高,差异均具有统计学意义(P<0.05)。结论合并糖尿病的老年肺结核CT征象具有一定的特殊性,在病变分布上累及双肺或多叶多见,大片状融合和合并多发空洞比例高。
Objective To study the CT imaging characteristics in elderly pulmonary tuberculosis patients with diabetes mellitus and to provide the basis for clinical diagnosis. Methods All patients were performed chest CT scan. 78patients of the pulmonary tuberculosis were divided into two groups according to whether or not they have diabetes, the pulmonary tuberculosis patients with diabetes mellitus were collected as a study group （n = 39cases） and the pulmonary tuberculosis patients only were considered a control group （n = 39cases）. The lesions area ,lesions shape and the prevalence of cha acteristic pathological changes like a large patch of fusion patchythe , multiple cavitates and multiple dendr - itic endobronchial dissemination were compared and analyzed between the two groups. Results The attack rate of bilateral lung were 84. 62% in the study gro - up, which was significantly higher than 61.54% in the control group with stati - stical difference. （χ^2=5. 278 ,P =0. 022）Compared with the control group, the prevalence of lesions shape involved two lobes or more in the study group was higher than that of the control group,which was 76. 92% vs. 53.85%,χ^2=4. 588, P = 0. 032. In the comparison of lesions shape, the frequency of effusion was higher while nodules, was lower in the study group with statistical difference,which were 43.59% vs. 20. 51% ,χ^2 =4. 768, P =0. 029 and 76. 92% vs. 53.85%, χ^2 = 4. 522, P = 0. 033 seperately. The results of CT imaging characteristics showed the frequency of large patch of fusion patchythe in the study group is higher than thatin the control group,which were 53.85% vs 28.21%, χ^2 =5. 299,P = 0. 021. Comp -ared with the control group, the frequency of multiple cavitates and multiple dendritic endobronchial dis- semination were higher with statistical difference. Conclusion The CT imaging of the pulmonary tuberculosis patients with diabe - tes mellitus has a certain degree of particularity. The proportion of lesions invol -ved the double lung or multiple lobes, a large patch of fusion patchythe and multiple cavitates were higher.
