65岁以上老年继发性肺结核影像学特点分析

Analysis of imaging characteristics of secondary pulmonary tuberculosis for people aged over 65

目的对65岁以上老年继发性肺结核影像学特点进行分析和探讨,以期进一步认识和掌握老年继发性肺结核的影像特点,提高临床诊治率。方法对48例老年继发性肺结核患者的临床及影像学资料进行回顾性分析。结果 48例患者中病变部位以上中肺野为主者28例,占58.33%,双肺发病者40例,占83.33%;病变性质中纤维空洞及空洞型病变患者有25例,占52.08%;病变形态中出现纤维索条影的患者有25例,占52.08%,出现斑点状或结节状影的患者有20例,占41.67%,出现团块状、不规则斑片状钙化的患者有26例,占54.17%。结论老年继发性肺结核分布广泛,影像表现多样,形态以多发空洞、干酪性肺炎、支气管播散等多见,且多种病变形态并存,治疗效果差,传染性强,应引起关注。

Objective To investigate and analyze the imaging characteristics of secondary pulmonary tuberculosis for people aged over 65, in order to gain further understanding and mastering of image characteristics of senile secondary pulmonary tuberculosis, and to increase the rate of clinical diagnosis. Methods The clinical and imaging data of 48 cases of elderly patients with secondary pulmonary tuberculosis were retrospectively analyzed. Results Above and middle lung fields were the main lesion position, which accounted for 58.33% as 28 cases among 48 cases. There were 40 cases with double lungs disease as 83.33%, 25 cases of cavity lesions and lesion fiber hollow as 52.08%, 25 cases of fibrous streaks of lesion as 52.08%, 20 cases of mottled or nodular shadows of lesion as 41.67%, and 26 cases of crumb and irregular patchy calcification as 54.17%. Conclusion Senile secondary pulmonary tuberculosis is widely distributed, which has various imaging expression. Its form mainly expresses by multiple hole, cheese pneumonia, bronchial spread, etc. Moreover, a variety of lesions usually coexist, and it has poor curative effect due to strong infectivity. More attention should be paid to it.
