孕妇甲型H1N1流感的影像学表现

Radiological manifestation of pregnant women with influenza A(H1N1)

目的研究孕妇甲型H1N1流感影像特点。方法回顾性分析经临床诊断证实的14例甲型H1N1流感孕妇的资料,所有病例均行胸部X线片及CT影像学检查,实验室检查。结果所有病例在出现临床症状后胸部影像学检查均有异常表现,轻症患者8例,其中6例为单个肺叶磨玻璃密度及片状高密度,2例双肺下叶片状高密度,3例伴少量胸腔积液;重症患者6例,表现为双肺多叶受累团絮状高密度,同时伴有胸腔积液及心包积液。结论甲型H1N1流感孕妇患者影像学征像为非特异性急性感染性病变,有一定特征性,影像学检查有助于其早期诊断及鉴别诊断。

OBJECTIVE To investigate the radiological manifestation of pregnant women with influenza A（H1N1）.METHODS The data of 14 women who had been pregnant for 28 to 40 weeks with influenza A（H1N1） aged from 21 to 33 were retrospectively analyzed.All of the cases underwent chest X-ray,CT examination and laboratory examination.RESULTS All of the cases had abnormal chest radiological manifestations after they developed clinical symptoms.There were 8 mild cases,of which there were 6 cases with ground glass and lamellar high density images in a single lung lobe,2 cases with lamellar high density images in both lower lung lobes,and 3 cases with small amounts of pleural effusion.The 6 severe cases had multiple massive high density images in both lungs accompanied by pleural and pericardial effusion.CONCLUSION The radiological manifestations in pregnant women with influenza A（H1N1） are non-specific acute infectious lesions with certain characteristics.Radiological examination is helpful for the early and differential diagnosis of influenza A（H1N1）.
