目的:总结甲型H1N1流感患儿胸部影像学表现。方法:回顾性研究经临床证实的62例患儿的胸部X线片及CT片。所有患儿均于入院前或入院后1天内拍摄X线胸片,5例患儿进行了胸部CT扫描,并于住院期间进行治疗评估性胸部X线摄片。结果:早期胸部X线片表现阳性者有42例,其中仅有肺炎样表现(肺内斑片状、片絮状、小絮状或磨玻璃样阴影等)的有34例,伴有胸膜炎4例,伴纵隔积气1例,伴肺段性不张1例,伴肺段性不张及胸腔积液1例,有肺水肿、肺出血样表现1例;余20例患儿胸部X线片表现为阴性。治疗后复查胸片,42例阳性者中41例转阴,1例遗留肺部纤维化。结论:胸部影像学检查在甲型H1N1流感患儿的病情评估、指导用药及治疗效果评价等方面有重要作用。
Objective: To summarize the chest radiographic findings of children with influenza A (H1N1). Methods: A retrospective study of 62 cases of clinically confirmed chest X-ray and CT films. All children underwent X-ray chest radiographs before admission or within 1 day after admission. Five children underwent chest CT scans and were evaluated for chest radiography during hospitalization. Results: There were 42 cases of early chest X-ray manifestations, of which only 34 cases of pneumonia-like manifestations (patchy lungs, flakes, small floc or ground glass-like shadow, etc.) with pleurisy 4 Cases, with mediastinal gas in 1 case, with pulmonary atelectasis in 1 case, with pulmonary atelectasis and pleural effusion in 1 case, pulmonary edema, pulmonary bleeding in 1 case; the other 20 cases of children with chest X-ray The film showed negative. After treatment, chest radiographs were retrospectively reviewed. Of the 42 positive cases, 41 were negative and 1 left pulmonary fibrosis. Conclusion: Chest imaging plays an important role in evaluating the condition of children with influenza A (H1N1), guiding the medication and evaluating the therapeutic effect.
