目的探讨H7N9亚型人禽流感的胸部CT早期表现。方法 8例经临床确诊的H7N9亚型人禽流感患者在发病后1周内接受胸部CT检查,回顾性分析其胸部CT图像,分析内容包括病变数目、分布、范围、病变形态及纵隔、胸膜改变等。结果 8例H7N9亚型人禽流感患者胸部CT扫描均有异常发现,共发现13个病灶,分布于上叶5个(38.5%),中叶1个(7.7%),下叶7个(53.8%)。CT上均表现为高密度实变,其中肺叶性或肺段性7例(87.5%),小斑片状1例(12.5%)。2例(25%)合并有结节状影。结论 H7N9亚型人禽流感胸部CT早期表现具有一定特点,CT有助于早期提示临床诊断。
Objective To investigate the chest CT manifestations of H7N9 subtype human bird flu. Methods Eight cases of clinically diagnosed H7N9 subtype avian influenza patients underwent chest CT examination within 1 week after onset. The chest CT images were retrospectively analyzed, including the number of lesions, distribution, range, pathological changes, mediastinal and pleural changes Wait. Results Thoracic CT scan of 8 H7N9 subtype avian influenza patients were found abnormally. Thirteen lesions were found in 5 of the upper leaves (38.5%), 1 of middle leaves (7.7%), 7 of lower leaves (53.8% ). CT showed high-density consolidation, of which lobular or pulmonary segmental in 7 cases (87.5%), small patchy in 1 case (12.5%). 2 cases (25%) with nodular shadow. Conclusion CT manifestations of chest X-ray of H7N9 subtype have certain characteristics in the early stage. CT can be helpful to early clinical diagnosis.
