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 analyze and discuss the imaging features of senile secondary pulmonary tuberculosis over the age of 65 in order to further understand and grasp the imaging characteristics of senile secondary tuberculosis and improve the clinical diagnosis and treatment rate. Methods The clinical and imaging data of 48 elderly patients with secondary pulmonary tuberculosis were retrospectively analyzed. Results Among the 48 cases, there were 28 cases (58.33%) with lung field above the lesion, 40 cases (40.33%) with lung disease and 25 cases (52.08%) with fibroids and cavitary lesions. Twenty-five patients (52.08%) had fibroinography in lesion morphology, 20 (41.67%) patients had speckled or nodular appearance, and there were massive and irregular patchy calcification 26 cases, accounting for 54.17%. Conclusions Elderly secondary tuberculosis is widely distributed, the images are diverse, multiple forms of cavity, cheese pneumonia, bronchial dissemination and other common, and a variety of lesions coexist, the treatment effect is poor, should be of great concern.
