目的探讨糖尿病合并肺结核的CT影像学特征,以提高CT诊断水平。方法收集2010年1月-2014年1月我院收治的60例糖尿病合并肺结核患者,回顾分析他们胸部CT影像中的病变分布特点和形态特征。结果本组60例患者中,发生在常见部位40例,非常见部位20例,多个肺段叶发病35例,CT主要表现为大片状、斑点片状和云絮状影,空洞,支气管播散树芽征,球状、结节状、团状影,弥散粟粒样小结节影等。结论糖尿病合并肺结核CT影像表现具有病变分布广泛,非常见部位不少见;病变形态多种多样,以渗出性病变、空洞及支气管播散树芽征为主,出现支气管播散树芽征时是活动性肺结核的标志。
Objective To investigate the CT features of diabetic patients with pulmonary tuberculosis in order to improve the diagnostic value of CT. Methods Sixty patients with diabetes mellitus complicated with pulmonary tuberculosis admitted in our hospital from January 2010 to January 2014 were retrospectively analyzed for their lesion characteristics and morphological features in CT images of the chest. Results The group of 60 patients, occurred in 40 cases of common parts, 20 cases of unusual parts, multiple pulmonary disease in 35 cases, CT mainly for large flakes, patchy and flocculent shadow, empty, bronchial Spreading tree bud sign, spherical, nodular, lumpy shadow, diffuse millet-like nodules and so on. Conclusions The manifestations of CT in diabetic patients with pulmonary tuberculosis are characterized by a wide range of lesions, not uncommon in uncommon sites, various morphological changes, exudative lesions, vacuoles and bronchial-disseminated tree buds. When bronchial disseminated buds appear, Active tuberculosis sign.
