[摘要] 目的 探讨影像学诊断不典型性肺结核的临床价值。方法 该次研究对象来源于方便选取该院2015年2月—2017年2月收治的不典型性肺结核患者60例,分别采用X线与CT检查,比较两种检查方式的确诊率与检查征象。结果 X线确诊率为78.3%,低于CT 95.0%,比较差异有统计学意义(P<0.05);53.3%为肿块或结节型,21.7%为肺叶实变或节段型,10.0%为空洞型,粟立结节型、下叶肺结核型及支气管内膜结核型各占5.0%。结论 CT相较于X线诊断不典型性肺结核临床价值更高。

[Abstracts] Objective This paper tries to evaluate the clinical value of radiographic diagnosis of atypical tuberculosis. Methods Convenient selection 60 cases of atypical tuberculosis treated in this hospital from February 2015 to February 2017 were selected and respectively adopted X-ray and CT examination, the diagnosis rate and signs of these two methods were compared. Results The diagnostic rate of X-ray was 78.3%, lower than CT of 95.0%, the difference was statistically significant(P<0.05); lumps or nodular type were 53.3%; 21.7% of lobular consolidation or segmental type; 10.0% of cavernous type; the millet nodular type, lower lobular tuberculosis type and endobronchial tuberculosis type accounted for 5.0% respectively. Conclusion The clinical efficacy of CT in the diagnosis of atypical tuberculosis is better than the X-ray.

肺结核为临床常见肺部感染性疾病,诱因为结核分歧杆菌,为当前致死人数最多的单一传染性疾病,对人类健康有着严重威胁。肺结核患者为结核分歧杆菌主要传染源,传播途径为呼吸道,机体健康者被结核菌侵袭后不一定发病,但机体抵抗力差或免疫力降低时便会发病。据统计全球每年超过800万人患上肺结核,致死者约为300万[1-3]。近年来不典型性肺结核患者数量越来越多,其临床表现缺乏特异性,胸部影像学检查特点为多变性[4],再加之检出病原菌的几率较低,故而易被漏诊或误诊。涂阳肺结核患者为不典型肺结核主要传染源,多与其他肺部疾病合并发生,诊断难度较大。目前临床多采用CT或X线诊断不典型性肺结核,现选取该院2015年2月—2017年2月收治的患者60例,探讨其诊断价值,现报道如下。
1 资料与方法
1.1 一般资料
该次研究对象来源于方便选取该院收治的不典型性肺结核患者60例,多数咳嗽且合并咳痰,部分痰中带血或胸痛。其中男性43例,女性17例,年龄为37~68岁,平均年龄为(48.7±7.5)岁。
1.2 检查方法
所有患者均行胸部X线与CT检查。……
