| 【摘要】目的：探讨并总结人感染H7N9禽流感病毒的胸部影像学特点。方法：回顾性分析人感染禽流感H7N9禽流感病毒的12例患者的影像学资料。所有患者均行胸部X线片和/或CT检查并随访。结果：12例患者的感染都进展为下呼吸道感染，并迅速发展为急性呼吸窘迫综合征。胸部影像主要表现为片状影（12例），磨玻璃影（9例），实变（9例），空气支气管征（9例），网格状改变（3例），胸腔积液（4例），纵隔及肺门淋巴结增大（3例）。9例肺部病变涉及多个肺叶，两下肺及右上肺多见。12例随访影像显示8例病情好转，4例病变恶化。结论：H7N9肺炎主要的影像学表现是段或叶的磨玻璃影和实变，并迅速波及双肺。CT能更加全面客观反映疾病的进程并评估其严重程度。 |
| 【Abstract】Objective：To investigate the imaging findings of human infection with H7N9 avian influenza virus.Methods:A novel avian influenza virus H7N9 infection in twelve patients was retrospectively analyzed.All patients underwent chest radiography and CT examination as well as in following up.Results:All 12 patients had progressing lower respiratory tract infection and developed rapidly to acute respiratory distress syndrome (ARDS).The imaging findings mainly included patchy shadows (n=12),ground glass opacities (n=9),consolidation (n=9) and air bronchogram (n=9).Reticular pattern (n=3),pleural effusion (n=4),mediastinal and hilar lymphadenopathy (n=3) could also be seen.Involvement of multiple lobes could be revealed in 9 patients,mostly in bilateral lower lobes and right upper lobe.Follow up images displayed improvement (8 patients) or worsening (4 patients)of disease.Conclusion:The imaging features of H7N9 pneumonia are segmental or lobar ground glass opacities and consolidation,which could rapidly progressed to bilateral lungs involvement.CT imaging is more comprehensive and objective to reflect the course of disease and to evaluate the degree of severity. |
