目的分析糖尿病合并肺结核的CT影像学特点,从而了解糖尿病合并肺结核病灶的变化规律,提高对该病的认识,为临床综合诊断提供依据。方法分析68例合并糖尿病的肺结核患者胸部CT特点,并与同期60例未合并糖尿病的肺结核病例进行对照,比较两组影像学特征。结果 68例糖尿病肺结核的病灶单独下肺叶受累的27例(39.71%),出现空洞的有47例(69.12%),支气管播散53例(77.94%)。结论合并糖尿病肺结核的患者CT影像学常表现的不典型:病变分布上常累及多肺段,以及肺结核的少见部位;形态上具有多形性,以干酪渗出病变为主,易于融合,易出现支气管播散,空洞发生率高。
Objective To analyze the features of CT images of diabetic patients with pulmonary tuberculosis so as to know the regularity of the changes of diabetic patients with pulmonary tuberculosis and improve their understanding of the disease so as to provide the basis for clinical diagnosis. Methods Sixty-eight patients with pulmonary tuberculosis complicated with diabetes were analyzed and compared with 60 cases of pulmonary tuberculosis without diabetes mellitus. The imaging features of the two groups were compared. Results There were 27 cases (69.12%) in 68 cases of pulmonary tuberculosis with lobular involvement alone, 39 cases (69.12%) with empty cavity, and 53 cases (77.94%) in bronchial dissection. Conclusions CT images of patients with diabetes mellitus tuberculosis usually show atypical features: the lesion distribution often involves multiple lung segments and the rare sites of pulmonary tuberculosis; the morphology is pleomorphic, with cheese exudative lesions predominant, easy to fuse, easy to appear Bronchial spread, high incidence of holes.
