目的探讨人感染H7N9禽流感的胸部影像表现.方法搜集5例临床确诊为人感染H7N9禽流感的患者,共摄X线胸片6次(复查2例),行CT扫描9次(复查4例).5例患者均有禽类接触史.结果 5例患者中,3例X线胸片表现为两肺大片状影;4例CT表现为双肺多叶、多段实变,无明显肺叶、肺段或特定体位分布趋势,实变内有明显的空气支气管征;3例大片肺实变呈均匀致密实变、磨玻璃样实变;相邻肺段实变融合或在叶间裂处相邻的肺叶实变扩展,2例可观察到病变越过叶间裂蔓延至邻近肺叶的现象;短期复查患者病变进展迅速,呈双肺多发磨玻璃影及广泛肺实变影像;5例均合并少量胸腔积液或胸膜增厚;无肺门、纵隔淋巴结肿大.结论胸部影像异常是诊断人感染H7N9禽流感的必要指标,CT能更清楚地显示人感染H7N9禽流感的影像征象.

Objective To study the imaging characteristics of Human infection with avian influenza A H7N9 virus patients.Methods Six chest X-ray examinations and Nine CT examinations were performed in 5 cases of Human infection with avian influenza A H7N9 virus that were verified by the Clinic.Results In the 5 cases,3 of 4 cases showed large areas of lung consolidation and bilateral lung involvement on chest X-ray.ALL the 4 cases showed multi-lobar or multi-segmental consolidation in bilateral lungs on CT images.There was no distribution tendency for any specific pulmonary lobes or segments.There was obvious air bronchogram in the consolidation.In 3 cases,The big consolidation appeared as homogeneous opacities and ground-glass appearance.Consolidation expanded along the pulmonary segment and coalesced together to form a pulmonary segment consolidation,The loci that crossed the interlobular fissure were observed in 2 cases.Early repeated examination showed rapid lesion progress with extensive lung consolidation or ground-glass opacity in both lungs.Small amount of pleural effusion or pleural thickening was noticed in 5 cases.The meditational lymph nodes enlargement was not observed.Conclusion The imaging abnormalities on the thoracic plain film are the clues to make the diagnosis of Human infection with avian influenza A H7N9 virus,and CT can detect the pulmonary abnormalities for more details.
