摘　　要：目的探讨人感染H7N9禽流感病毒性肺炎的影像学表现。方法回顾性分析笔者医院收治的10例确诊为人感染H7N9禽流感病毒性肺炎患者的临床及影像学资料。结果 10例患者均行X线和CT检查。9例患者呈多灶多肺叶分布,以两肺下叶最多;7例病灶呈磨玻璃密度影(ground glass density,GGO)或GGO合并大片状实变;5例小叶间隔增厚、3例支气管血管束增粗;5例实变肺组织内见充气支气管征。其他征象:少量胸腔积液4例,纵隔淋巴结肿大伴钙化1例。结论人感染H7N9禽流感肺炎具有一定的影像学特征,影像学检查有助于监测病情变化。Objective To study the imaging findings of novel avian - origin influenza A （H7N9） pneumonia. Methods The clini- cal and imaging data of 10 patients confirmed with human infection H7N9 avian influenza viral pneumonia were retrospectively analysis. Results All patients underwent chest X - ray and spiral CT examinations. Multiple lesions were showed in the multiple lung lobes in 9 eases of patients, and the lesions were most located in the left and right lower lobes. Seven cases of lesions showed ground glass density （GGO） , or GGO merger a large patch of consolidation. Five cases of the interlobular septal thickening, 3 cases of the bronchovascular bundles enlargement, 5 cases of air bronehogram were showed in the CT imagings. The others concluded with 4 cases of a small amount of pleural effusion and 1 case of lymph node enlargement. Conclusion Novel avian - origin influenza A （H7N9） pneumonia has certain im- aging features in the CT and chest X - ray, and imaging examinations ean help to monitor the disease progression.
