目的探讨甲型H1N1流感肺炎的影像表现。方法回顾性分析2010年至2014年符合诊断标准的30例甲型H1N1流感肺炎患者的X线及CT影像学资料。结果 X线表现:16例肺部纹理增多,以双下肺内多见;11例单侧肺部斑片状影,多靠近心膈区;3例症状不明显。CT表现:14例左侧肺部下叶出现多个小叶磨玻璃影,且融合成片状,可见支气管结节征。10例两侧肺部出现多发性磨玻璃影以及局部灶性实变影,分布在中下肺部的中外带,可见支气管充气征。6例肺部见实质性渗出影,肺内呈斑片状或片状实变影,累及周围多个肺叶,密度不均匀,边缘模糊。结论影像学表现对于确定甲型H1N1流感肺炎的病变范围以及病程发展变化具有重要意义,并为甲型H1N1流感肺炎的早发现早治疗奠定了基础。
Objective To investigate the imaging manifestations of influenza A (H1N1) pneumonia. Methods The X-ray and CT imaging data of 30 patients with influenza A (H1N1) pneumonia who met the diagnostic criteria from 2010 to 2014 were retrospectively analyzed. Results X-ray findings: 16 cases of lung texture increased to more common in the double lower lung; 11 cases of unilateral lung patchy shadow, and more near the diaphragm area; 3 cases were not obvious symptoms. CT manifestations: 14 cases of left lobe of the lower lobes appeared lobular glass shadow, and fused into a sheet, showing bronchiectasis. 10 cases of both sides of the lung appeared multiple ground glass and local focal refraction, located in the middle and lower lung in the band, showing signs of bronchial inflatable. 6 cases of pulmonary see substantial exudative shadow, the lung was patchy or lamellar consolidation of the shadow, involving multiple lobes around the uneven density, blurred edges. Conclusion The imaging findings are of great significance for the determination of the extent of the disease and the course of disease progression of Influenza A (H1N1) pneumonia, and lay a foundation for early detection and early treatment of influenza A (H1N1) pneumonia.
