目的分析糖尿病并发肺结核的 CT表现，以提高CT诊断水平。方法 随机 选取糖尿病并发肺结核104例为观察组， 单纯肺结核患者104例为对照组，对两 组患者的胸部CT表现进行比较分析。结 果 观察组患者病灶发生于肺结核少见部 位较对照组多，两组比较有统计学差异 (P<0.05)；肺结核常见部位两组比较不 具统计学差异(P>0.05)。观察组患者病 灶分布范围较对照组广，两组比较有统 计学差异(P<0.05)。观察组患者大片实 变影较对照组大，两组比较有统计学差 异(P<0.05)。观察组患者空气支气管征 及多发虫蚀样空洞较对照组多，两组比 较有统计学差异(P<0.05)。结论 糖尿病 并发肺结核具有两肺病灶分布范围广， 少见部分也多见，病灶大，多叶段分布 的片状影，大片状影内见空气支气管征 及多发虫蚀样空洞等特点。

Objective Analysis of CT manifestations of Diabetes complicated with tuberculosis ,in order to improve the level of CT diagnosis. Methods 104 cases of diabetes complicated with tuberculosis were randomly selected as the study group,104 cases of patients with pulmonary tuberculosis alone as a control group。Comparison of two groups of patients with chest CT performance analysis. Results Lesions occur in the rare site of tuberculosis, The number of patients in the observation group is more than in the control group.There were significant differences between the two groups(P<0.05).In common site of tuberculosis, Comparison of the two groups is not a statistically significant difference(P>0.05). The distribution range of lesions of the observation group is wider than in the control group, Comparison of the results of the two groups were significantly different(P<0.05). Air bronchogram and multiple moth-eaten holes of the observation group is more than the control group. Conclusion Diabetes complicated with tuberculosis, Two lung lesions distribution range is wide, Rare part is also more common, The lesion is large, Patchy distribution of multi-leaf segments, May have air bronchograms and multiple moth-eaten holes large patchy.
