目的探讨新型甲型H1N1流感肺炎患者胸部CT及X线表现,以提高诊断准确性。方法回顾分析15例新型甲型H1N1流感肺炎患者胸部CT和X线资料,研究病变影像学特点、部位、数目及演变。结果肺实变13例,磨玻璃9例,支气管气像6例,胸腔积液4例,胸膜增厚3例,纵隔内见多发淋巴结5例,轻症组与重症及危重症组之间均无统计学差异(P>0.05);肺实变及磨玻璃病变部位:双肺多叶10例,单肺单叶5例,轻症组与重症及危重症组之间有统计学差异(P<0.05);肺实变及磨玻璃经治疗后吸收、减轻11例、未见变化2例、加重2例,轻症组和重症及危重症组之间均无统计学差异(P>0.05)。结论新型甲型H1N1流感肺炎患者胸部CT和X线表现以肺实变和磨玻璃改变为主,伴胸膜及淋巴结异常等多种表现。
Objective To investigate the chest CT and X-ray manifestations of patients with new type A (H1N1) pneumonia and to improve the diagnostic accuracy. Methods The chest CT and X-ray data of 15 patients with new type A (H1N1) pneumonia were retrospectively analyzed to study the imaging features, location, number and evolution of lesions. Results 13 cases of lung consolidation, ground glass in 9 cases, bronchial gasography in 6 cases, pleural effusion in 4 cases, pleural thickening in 3 cases, multiple mediastinal lymph nodes in 5 cases, mild cases and severe and critically ill patients were There was no significant difference (P> 0.05). The areas of lung consolidation and ground glass lesions included 10 cases of double-lobed multi-lobe and 5 cases of single-lobe single lobe. There was a significant difference between mild group and severe and critically ill group <0.05). There was no difference between the mild group and the severe and critically ill patients (P> 0.05). There were 11 cases of lung consolidation, . Conclusion The CT and X-ray manifestations of chest X-ray in patients with new type A (H1N1) pneumonia are mainly pulmonary consolidation and ground glass changes, with pleural and lymph node abnormalities.
