【摘要】：目的探讨急性白血病患儿肺部感染的薄层CT表现,提高薄层CT在诊断肺部感染中的价值。方法选取2005-2014年在医院确诊为急性白血病且住院期间患过肺炎的患儿120例,回顾性分析患儿肺部薄层CT的表现,总结急性白血病肺部感染的CT表现特点。结果 77例真菌性肺炎患儿以肺部结节或团块影为主要CT表现,占66.2%,其中有74.5%的结节或团块内出现了"新月征",56.9%结节或团块边缘出现了晕征;24例病毒性肺炎中,79.2%表现为双肺弥漫性改变,约50.0%病变呈现磨玻璃样改变;19例细菌性肺炎中有14例表现为肺叶或肺段的大片高密度影,63.5%合并支气管充气征。结论急性白血病患儿肺部感染的CT表现多种多样,真菌性肺炎是最常见的类型,CT表现为合并"新月征"和"磨玻璃晕征"的结节或团块影。
[Abstract]:Objective to investigate the thin slice CT findings of pulmonary infection in children with acute leukemia and to improve the value of thin slice CT in the diagnosis of pulmonary infection. Methods 120 children with acute leukemia and pneumonia in hospital from 2005 to 2014 were selected. The CT features of pulmonary infection in children with acute leukemia were analyzed retrospectively. Results the pulmonary nodules or lumps were the main CT findings in 77 cases of fungal pneumonia. 66.2% of them had "crescent sign" in 74.5% of the nodules or mass. 79.2% of the 24 cases of viral pneumonia showed diffuse changes in both lungs. About 50.0% of the 19 cases of bacterial pneumonia presented with ground-glass changes. 14 of the 19 cases of bacterial pneumonia showed massive hyperdense bronchitis in the lobes or segments of the lung. Conclusion CT findings of pulmonary infection in children with acute leukemia are varied. Fungal pneumonia is the most common type of CT findings associated with "crescent sign" and "ground glass halo" nodule or mass shadow.
