56例甲型H1N1流感合并肺炎的影像分析

目的探讨甲型H1N1流感合并肺部炎症的影像表现。方法回顾性总结分析56例甲型H1N1流感合并肺部炎症患者胸部CT的影像表现。结果①56例均以大小不等的云片状及絮团状的炎性实变影为基本影像表现;②54例病变以肺外围向肺门发展为特征;③41例病变范围广,发展速度快,双侧广泛分布;④36例累及胸膜,易合并胸膜增厚、胸腔积液及气胸;⑤9例病变发展可有支气管通气征;⑥6例合并纵隔淋巴结肿大。结论影像学检查有助于肺部损害的客观评估及并发症的早期诊断,对甲型H1N1感染者预后至关重要。

56 cases of influenza A H1N1 influenza with pneumonia in image analysis

Objective To investigate the A-H1N1 influenza imaging findings with pulmonary inflammation. Methods Retrospectively analyzed 56 cases of Influenza A H1N1 influenza in patients with pulmonary inflammation in the performance of chest CT images. Results ①56 cases are different sizes of cloud sheet and the floc-shaped shadow of inflammatory consolidation as the basic imaging performance;②54 cases lesions in the lung characterized by the development of the periphely to the hilum;③ cases lesions broad in scope,the development of fast,bilateral widely distributed;④36 cases involving the pleura,easy to merge pleural thickening,pleural effusion and pneumothorax ⑤9 cases lesion may have bronchial ventilation sign;⑥ 6 cases with mediastinal lymph nodes.Conclusion The imaging studies help to an objective assessment of lung damage and complications of early diagnosis,influenza A H1N1 infection on prognosis is essential.
