白血病肺部并发症的影像学分析

目的　分析白血病肺部并发症影像学特点 ,提高诊断白血病肺部并发症的水平。方法　分析 2 0 0例白血病肺部并发症的影像学特点。结果　并发症的致病因素 :单一细菌感染占 3 3 .5% (67例 ) ,细菌混合感染占 3 5% (70例 ) ,真菌感染占 3 .5% (7例 ) ,真菌细菌混合感染占 5% (10例 ) ,致病菌不明占 2 3 % (46例 )。影像学表现 :肺纹理改变 84例 (42 % ) ,肺实质病变 116例 (58% ) ,胸膜改变 2 9例 (14 .5% ) ,胸腔积液 19例 (9.5% ) ,肺门或纵隔改变 40例 (2 0 % )。结论　白血病肺部并发症以感染为多见 ,诊断应结合临床和实验室检查。此外治疗后复查对照亦有助于鉴别

The Analysis of Imaging Characteristics of Pulmonary Complications in Leukemia

Objective To improve the diagnostic level of pulmonany complications of leukemia by analysing imaging characteristics.Methods The imaging findings of pulmonary complications were analysed in 200 cases with leukemia.Results The pathogenic agents of pulmonary complications included:infection of single type of bacteria in 33.5%(67 cases),mixed bacteria infection in 35%(70 cases),fungal infection in 3.5%(7 cases),fungal infection combined with bacteria infection in 5%(10 cases),unknown pathogenic agents in 23%(46 cases).The radiologic findings were as follows:the change of lung markings in 84 cases(42%),lung parenchyma lesion in 116 cases(58%),pleura lesion in 29 cases(14.5%) ,pleural effusion in 19 cases(9.5%), hilum of the lung or mediastina lesion in 40 cases (20%).Conclusion Pulmonary complications of leukemia are mainly pulmonary infection.The diagnosis of this lesion has to combined with clinical data and laboratory test,repeat radiography after treatment is also helpful in differential diagnosis.
