白血病肺部浸润的CT表现

CT manifestations of lung in patients with leukemia pulmonary infiltrates

目的 :探讨白血病胸部浸润的CT表现 ,评价白血病肺部浸润的CT诊断价值。方法 :回顾性分析我院确认的12例白血病患者的胸部白血病细胞浸润的CT(HRCT)表现。结果 :白血症患者发生胸部浸润的CT表现多种多样 ,主要为小叶间隔增厚、外周支气管血管间质增厚、结节影 ,毛玻璃状改变 ,气腔实变等。这些表现与白血病细胞浸润肺的途径相一致 ,但不具特异性。结论 :白血病患者出现胸部症状时 ,应考虑到肺浸润的可能 ,CT有助于肺浸润的诊断 ,但应与其他并发症如感染相鉴别。

Objective:To describe CT manifestations of lung in patients with leukemia pulmonary infiltrates as well as to impuove CT recognition of leukemia pulmonary infiltrates.Methods:High-resolution CT(HRCT) findings of lung in 12 patients with leukemia pulmonary infiltrations were reviewed.Results:HRCT findings of leukemia pulmonary infiltration has a great variety,the main findings are peribronchovascular interstitial thickening,parenchymal nodules,interlobular septal thickening,ground-glass opacity,air-space consolidation and so on.These findings are consistent with the pattern of the leukemic cells to infiltrates the lung.Conclusion:All the findings are of non-specificity.The presence of pulmonary infiltrates should be consiedred when complication occurs in patients with leukemia.Although other processes should be excluded,CT is helpful in detectng leukemia pulmonary infiltrates.
