目的探讨糖尿病合并肺结核的CT诊断特点。方法回顾分析80例患者的临床资料。结论 CT对糖尿病合并肺结核时大多能做出正确的诊断,但当胸部病变表现不典型或临床资料不全时,CT诊断可能比较困难,诊断时需与肺炎、肺癌等疾病鉴别。对于未发现糖尿病的肺结核病例,出现广泛叶段分布的大片状、斑块状病灶,其内有多发的无壁空洞,或者经抗结核治疗病灶变化不多的,甚至出现病灶范围扩大,空洞增大,出现播散灶时,均应考虑糖尿病的存在,应进行糖尿病的系列检查,以明确诊断以免延误治疗。
Objective To investigate the diagnostic features of CT in diabetic patients with pulmonary tuberculosis. Methods The clinical data of 80 patients were retrospectively analyzed. Conclusions Most of the CT diagnosis of diabetic patients with pulmonary tuberculosis can be correctly diagnosed. However, CT may be difficult to diagnose when the manifestations of chest disease are not typical or the clinical data are incomplete. The diagnosis should be based on the identification of diseases such as pneumonia and lung cancer. For cases of pulmonary tuberculosis that have not been found with diabetes, there is a large patchy, plaque-like lesions with extensive leaf segment distribution. There are multiple non-wall-empty holes in them or there are few changes in the lesions treated by anti-TB therapy. Increase, appear disseminated stove, should consider the existence of diabetes, diabetes should be a series of tests to confirm the diagnosis in order to avoid delay treatment.
