目的探讨老年性糖尿病合并肺结核的影像学特征。方法回顾性分析35例老年性糖尿病合并肺结核患者的影像学资料。结果老年性糖尿病合并肺结核病灶可位于肺的各个区域,除肺结核常见好发部位外还可发生于其他肺叶,多位于中叶、舌叶和下叶基底段,病灶形态多为实变和空洞且伴有两肺播散。血糖控制良好的患者经正规抗结核治疗后肺结核有明显的好转征象,而高血糖状态可加重肺结核的恶化。结论老年性糖尿病合并肺结核影像学表现与一般肺结核影像学表现有显著的差异。血糖控制良好与否影响着肺结核病变发展和转归,而肺结核影像学的动态变化从侧面反映糖尿病血糖控制的良好与否。
Objective To investigate the imaging characteristics of senile diabetes with pulmonary tuberculosis. Methods Retrospective analysis of 35 cases of elderly patients with diabetes mellitus and pulmonary tuberculosis imaging data. Results Senile diabetes mellitus combined with pulmonary tuberculosis can be located in various regions of the lung, in addition to the common tuberculous sites can occur in other lung lobes, mostly in the middle leaves, tongue and lower basal segments, the lesions are mostly solid and empty form and with There are two lungs spread. Patients with well-controlled glycemic control had marked signs of improvement in tuberculosis after formal anti-TB treatment, whereas hyperglycemia exacerbated tuberculosis. Conclusion There is a significant difference between the imaging findings of senile diabetes mellitus and pulmonary tuberculosis in imaging. Whether the control of blood glucose is good or not affects the development and prognosis of pulmonary tuberculosis, and the dynamic changes of tuberculosis imaging reflect the good or not of the control of diabetes mellitus from the side.
