肺结核这一严重损害身体健康的传染病,虽然近年来患病率逐年递减,但是,随着人口基数的不断增加,患者仍较多。及时、准确地诊断,对患者的治疗和愈后有很大影响。尤其是急性粟粒性肺结核,它常是由大量的结核杆菌一次侵入血液循环,所引起的急性全身血行播散型结核病的一部分。起病急骤,有全身毒血症状。X线表现大多为大小一致、分布均匀的粟粒状均匀密度增高影。结合临床,一般不难确诊。但在疾病早期,透视下不够明显,常不能及时做出诊断,或由于结核菌侵入血液的菌量与毒力不同及机体抵抗力的强弱,可使粟粒性阴影有粗细不同和分布不均的表现,随着粟粒性肺结核趋向好转或进展的不同变化,也可使粟粒性肺结核的X线表现发生不同的变化,易于误诊。 Although TB ​​is a contagious disease that seriously damages health, its prevalence has been decreasing year by year. However, with the population increasing, more people are still suffering from it. Timely and accurate diagnosis of patients with treatment and prognosis have a great impact. In particular, acute miliary tuberculosis, which is often part of an acute systemic hematogenous disseminated tuberculosis caused by a single invasion of the bloodstream by a large number of Mycobacterium tuberculosis. Rapid onset, systemic symptoms of poisoning. X-ray performance are mostly the same size, uniform distribution of miliary uniform density increased shadow. Combined with clinical, generally not difficult to diagnose. However, early in the disease, under fluoroscopy is not obvious enough, often can not make a timely diagnosis, or due to tuberculosis bacteria invade the blood of bacteria and virulence and the strength of different body resistance, the shadow can have a different size and uneven distribution of miliary shadow The performance of miliary tuberculosis tends to improve or progress with different changes, but also make the miliary tuberculosis X-ray showed different changes in performance, easy to misdiagnose.
