摘要
目的探讨甲型H1N1流感胸部HRCT表现。方法回顾性分析163例临床确诊为甲型H1N1流感患者的172次胸部HRCT扫描（复查9例）资料，采用标准肺窗和纵隔窗观察图像，分析胸部HRCT影像表现。结果97例胸部HRCT未见异常，其余66例HRCT主要表现为：（1）肺实质和间质同时受累，磨玻璃密度影35例（53．0％），小叶中心结节30例（45．5％），小叶内间质及小叶间隔增厚31例（47．0％），网状结节影8例（12．1％），单小叶炎症19例（28．8％），实变15例（22．7％），肺不张3例（4．5％），条索影2例（3．0％）。（2）胸膜炎症：右侧胸膜炎症8例，左侧胸膜炎症5例，双侧胸膜炎症19例。（3）纵隔淋巴结和腋窝淋巴结肿大7例。（4）抗病毒治疗后病灶吸收快。结论甲型H1N1流感患者胸部HRCT影像表现多样，类似病毒性肺炎表现，可见肺实质和肺间质炎症、胸膜炎症和纵隔淋巴结肿大。
Objective To explore the chest features of patients with the novel influenza type A H1N1 on HRCT. Methods One hundred and seventy-two chest HRCT examinations on 163 cases with Influenza type A H1N1 （9 cases were reexamed） were retrospectively analyzed using standard pulmonary window and mediastinal window, respectively. HRCT imaging appearances were summarized. Results Ninety-seven cases showed normal on chest HRCT, while the others showed abnormalities of parenchymal and interstitial. Among them, HRCT identified ground-glass opacity in 35 cases （53.0%） , centrilobular nodules in 30 cases （45.5%） , thickening of intralobular septa in 31 cases （47.0%） , intralobular thin reticulation and micro-nodule in 8 cases （ 12. 1% ）, single-lobular inflammation in 19 cases （28. 8% ）, consolidation of lung （ the large consolidation and multiple small consolidations ） in 15 cases （ 22. 7% ） , pulmonary atelectasis in 3 cases （4. 5% ）, and irregular lines in 2 cases （3.0%）. Pleurisy was also revealed including 8 cases with right pleurisy, 5 cases with left pleurisy, and 19 cases with bilateral pleurisy. Mediastinal and axillary lymphadenopathy were found in 7 cases, who were spared of pleural effusion. All above abnormalities resolved quickly after anti- virus treatment. Conclusion Parenchymal and interstitial abnormalities, mediastinum and axillary fossa lymphadenopathy, and pleural effusion were the common findings on HRCT in patients with Influenza type A H1N1, which were similar to those of other viral pneumonia.
