高分辨率CT对系统性红斑狼疮肺部病变的诊断价值

Diagnostic value of high-resolution CT in lung disease of systemic lupus erythematosus patients

目的探讨高分辨率CT（HRCT）对系统性红斑狼疮（SLE）肺部病变的诊断价值。方法回顾性分析临床确诊有肺部浸润的SLE患者28例肺部CT及HRCT表现。结果28例患者均表现为不同程度的肺间质纤维化，以两肺外周分布为主，小叶间隔增厚及磨玻璃样密度为其常见表现。结论应用HRCT检查可以帮助确定SLE浸润肺的程度，并能初步估计预后。小叶间隔增厚、磨玻璃样密度影是病变的早期活动性表现，蜂窝状囊腔改变为后期表现。

Objective To investigate the diagnostic value of high-resolution CT （HRCT） with systemic lupus erythematosus （SLE） lung lesions. Method Retrospective analysis of clinical diagnosis of SLE have pulmonary infiltration in patients with CT and 28 cases of lung HRCT performance was Conducted. Result 28 patients showed different degrees of pulmonary fibrosis to mainly peripheral distribution, lobular septal thickening and ground-glass density in the performance of its common. Conclusions HRCT check can help determine the extent of pulmonary infiltration SLE, and preliminary estimates of prognosis. Lobular septal thickening and ground-glass density are the early performance of SLE,while honeycomb cysts change is the peature in advanceal stage.
