摘　　要： 目的探讨广东佛山市在校青少年学生新发活动性肺结核的临床及CT影像学表现,提高对学生活动性肺结核的诊断水平。方法搜集经临床诊断的39例新发活动性肺结核青少年学生及同期随机抽取的78例新发活动性肺结核非学生成人群的临床和影像学资料,并对病变部位、影像学表现及临床症状进行对照统计分析。结果学生组咳嗽、咯血发病率分别为28.21%、10.26%,低于非学生组的78.21%、26.92%,两组间差异有统计学意义(P<0.05),Ⅱ、Ⅲ区域及≥3个肺叶病变位置分布上,两组差异有统计学意义(P<0.05),学生组小叶样肺实变、亚段及段性肺实变、叶性肺实变、网状影和细线影、索条影、无壁空洞、薄壁空洞、肺门及纵隔淋巴结肿大发病率与非学生组比较,差异有统计学意义(P<0.05)。结论学生组与非学生组活动性肺结核临床表现、病变分布及CT征象方面均存在一定差异,由于学生人群临床症状不典型,应重视学校日常肺结核可疑症状的筛查,主动发现病人;影像表现上学生人群好发部位典型,病灶范围较为局限,节段性分布小叶中心结节影为最常见。 Objective To explore the clinical and CT imaging manifestations of newly active pulmonary tuberculosis in adolescent students in Foshan,Guangdong,and to improve the diagnostic level of active pulmonary tuberculosis in students.Methods The clinical and imaging data of 39 students clinically diagnosed with newly active pulmonary tuberculosis and 78 randomly selected non-students adults with newly active pulmonary tuberculosis at the same period were collected,and a comparative statistical analysis of the pathological location,imaging manifestations and clinical symptoms was performed.Results The incidence of cough and hemoptysis in the student group were 28.21%and 10.26%,respectively,which were lower than those in the non-student group(78.21%and 26.92%),the difference between the two groups was statistically significant(P<0.05).The difference in the lesion location distribution at regions II and III and more than 3 pulmonary lobar lesions between the two groups was statistically significant(P<0.05).The differences in the incidences of lobular lung consolidation,subsegmental and segmental lung consolidation,lobar lung consolidation,reticular and fine line shadows,cord shadows,unwalled cavitation,thin-walled cavitation,hilar and mediastinal lymph node enlargement between the student group and the non-student group were statistically significant(P<0.05).Conclusion There were certain differences in the clinical manifestations,lesion distribution and CT signs of active pulmonary tuberculosis between the student group and the non-student group.Because the clinical symptoms of the student group are not typical,it is necessary to pay attention to the routine screening of suspicious symptoms of tuberculosis in school and to find the patient actively.The imaging manifestations show that the common sites of the student population are typical,the scope of the lesion is relatively limited,and the most common image is the segmental distribution of the central lobular nodules.
