目的:探讨耐多药肺结核的影像学特点。方法:收集内蒙古包钢第三职工医院资料完整的271例耐多药与不耐药肺结核患者,对病灶分布、形态及动态变化进行分析。结果:耐多药肺结核侵犯3个以上肺叶和毁损肺的患者较多(P<0.05),以播散、实变、空洞及毁损肺影像表现为主(P<0.05),病灶吸收病例少,恶化病例多(P<0.01)。结论:耐多药肺结核肺内病灶广泛,病变形态多样,病变活动明显,常表现为重症肺结核,治疗效果不佳。
Objective: To investigate the imaging features of MDR-TB. Methods: A total of 271 patients with multidrug-resistant and drug-resistant pulmonary tuberculosis were collected from the Third Staff Hospital of Inner Mongolia Baotou Steel Co. Ltd., and their distribution, morphology and dynamic changes were analyzed. Results: Most patients with multidrug-resistant pulmonary tuberculosis inflicted more than 3 lung lobes and destroying lungs (P <0.05), mainly showed disseminated, defoliating, empty and damaged lung images (P <0.05) The number of worsening cases (P <0.01). Conclusion: Multidrug-resistant pulmonary tuberculosis has a wide range of intrapulmonary lesions, diverse lesions and obvious pathological changes. It often presents with severe pulmonary tuberculosis and its treatment effect is poor.
