不同年龄段干酪为主型肺结核影像学特征分析

The analysis of cheese predominant type tuberculosis proportion and imaging characteristics at different ages

目的 探讨干酪为主型结核在不同年龄阶段肺结核的比例及影像学特征,以提高临床认识。方法回顾性收集经病理或临床证实的肺结核患者484例,按照年龄进行分组,统计并对比各组干酪为主型结核的发病情况,总结干酪性肺结核影像学特征。结果 484例肺结核中108例为干酪为主型;干酪为主型在2~15岁组发病率为66.6%(24/36),16~30岁发病率为26.2%(22/84),31~45岁发病率为11.9%(16/168),46~60岁发病率为29.5%(26/88),61岁以上发病率为18.5%(20/108)。108例干酪为主型结核肺实变、支气管黏液栓及肺内结节发生率分别为87.0%、69.4%及65.0%。结论 结核发病年龄越小,越应该警惕干酪为主型结核可能,其影像学常表现为不同形态的实变、支气管黏液栓及肺内结节,胸膜病变少见。

Objective To discuss cheese predom inant type tuberculosis proportion and imaging characteristics at different ages,improve its diagnosis and avoid misdiagnosis.Methods Retrospective analysis the CT signs and clinical data of 484 cases tuberculosis,confirm ed by pathologically or clinically.All cases were divided into different groups according to the age.The cheese predom inant type tuberculosis proportion and imaging characteristics were com pared.Results One hundred and eight cases of cheese predom inant type tuberculosis were proved in all 484 pulm onary tuberculosis patients.Cheese predom inant type tuberculosis accounted for 66.6%(24/36)of the total in the 2〜15 age group,26.2%(22/84)in the 16~30 age group,11.9%(16/168)in the 31〜45 age group,29.5%(26/88)in the 46~60 age group,and 18.5%(20/108)in the 61-over age group.The incidence rates of lung consolidation,bronchial m ucus plug and pulm onary nodules in 108 cases of ca se〜dom inated tuberculosis were 87.0%,69.4%and 65.0%respectively.Conclusion The younger the age of pulm onary tu b erculosis,the more wary cheese predom inant type tuberculosis should be take into consideration.C heese predom inant type tuberculosis often show different forms of consolidation,bronchial m ucus plug and pulm onary nodules,while pleural lesions is rare.
