球形肺结核的CT鉴别诊断分析

The Differential Diagnosis of CT in Spherical Tuberculosis

目的：分析CT检查球形肺结核影像学表现特征,总结其鉴别诊断要点。方法：选择2013年4月-2015年1月笔者所在医院收治的58例球形结核患者作为研究对象,所有患者均经过病理、CT等检查确诊为球形肺结核,收集患者的CT检查资料,分析球形肺结核的鉴别特征。结果：本组患者中单发构成比高于多发构成比。病灶1~3 cm的病灶构成比为55.17%,显著高于〉3 cm和〈1 cm的病灶构成比。病灶边缘清楚者构成比为43.10%,占比最高。强化模式中,无强化者构成比为36.36%,显著高于其他模式。结论：螺旋CT检查可发现球形肺结核的特征性,可依据其CT表现鉴别特征指导临床诊断。

Objective：To analyze the imaging features of pulmonary tuberculosis in CT, and to sum up the main points of differential diagnosis.Method：58 patients with pulmonary spheral tuberculosis in our hospital form April 2013 to January 2015 were selected as the research objects,all the patients were confirmed by pathology, CT, and so on,the CT examination of the patient＇s data were collected, and the identification features of pulmonary spheral tuberculosis were analysed.Result：In this group of patients, the ratio of single component was higher than that of multiple.Lesion size 1-3 cm lesions constitute 55.17%,which was significantly higher than that of 3 cm and 1 cm up than lesions.Lesions edge clear composition ratio was 43.10%, the highest proportion. Not improved mode, strengthen the proportion was 36.36%,which was significantly higher than other models.Conclusion：Spiral CT examination can find the characteristics of the spherical pulmonary tuberculosis, and can guide the clinical diagnosis according to the characteristics of CT.
