白血病肺部浸润的CT表现

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。

CT manifestations of lung in patients with leukemia pulmonary infiltrates

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.
