| 【摘要】目的：探讨人感染H7N9禽流感的胸部影像特点。方法：搜集13例经临床确诊为人感染H7N9禽流感患者的临床和影像学资料，分析其胸部影像表现。所有患者均行胸部X线检查，其中10例行胸部CT检查。结果：13例均表现为双肺多叶、多段实变，实变内有明显的空气支气管征。其中8例下肺病变重于上肺，5例右肺病变重于左肺；9例以肺实变为主，3例以实变为主。病变可越过叶间裂蔓延至邻近肺叶。所有病例均在发病后2～5d迅速发展，发病后6～18d病变范围开始缩小。病灶吸收后显示为条索状、网格状及蜂窝状影。结论:人感染H7N9禽流感的胸部影像表现有一定特点，对指导临床治疗有重要意义。 |
| 【Abstract】Objective：To investigate the chest imaging features in patients with H7N9 subtype avian influenza virus infection.Methods：The clinical and imaging materials of 13 patients with H7N9 subtype avian influenza virus infection were collected and the chest imaging manifestations were analyzed.All patients had chest radiography and 10 patients underwent chest CT.Results:All patients showed multi lobar or multi segmental consolidation in bilateral lungs,obvious air bronchogram could be assessed within consolidation.The abnormalities were more severe in lower lobes (n=8) and in right lung than in the left (n=5).The imaging features mainly manifested as consolidation (n=9) and consolidation with ground glass opacities (n=3).Pulmonary consolidation could extend across inter lobar fissure and involve the adjacent lobe.All patients had the disease rapidly progressed 2~5d after onset and gradually absorbed after 6~18d,demonstrated as linear，reticular and honeycomb patterns.Conclusion:Certain characteristic findings could be revealed in H7N9 subtype human avian influenza infection,which is of significance in guiding clinical treatment． |
