肾移植术后肺巨细胞病毒感染影像学特点

Imaging Features of the Patients with Cytomeglovirus Infection after Kidney Transplantation

目的:探讨肾移植术后肺巨细胞病毒感染的胸部X线表现,以期早期诊治。方法:根据临床表现及实验室检 测证实的12例肾移植术后巨细胞病毒感染的患者,动态观察其胸部X ray改变及特点。结果:肺部巨细胞病毒感 染,多发生在术后10～12周,肺部X ray变化快,主要表现为早期肺纹理增粗、增多、边缘模糊。随病变发展,肺内 可见多发的渗出性病灶,单侧或双侧病变,重症可呈斑片状或大片状融合性模糊影,临床表现凶险。本组12例,1 例发生ARDS死亡,余11例经综合治疗病变吸收治愈。结论:胸部X 摄片是诊断肾移植术后巨细胞病毒感染的重 要依据,动态观察对判断预后有重要价值。

Objective:To study chest X-ray manifestation of CMV infection after kidney transplantation to improve earlier diagnosis.Methods:Dynamically observing chest X-ray features and transformation of 12 cases with CMV infection after kidney transplantation.The diagnosis in all cases were confirmed by clinical findings and laboratory examination.Results:Most CMV infection occulted within 10~12 weeks after the operation.The chest X-ray manifestation changed quickly.Radio graphs of patients showed only non-specific per bronchial and per vascular markings at earlier period.With the development of pathological changes, radiographic abnormalities turned to patchy infiltrates in one or both lung fields. In some severs cases,radio graphic findings rangeved from patchy infiltrates to lobber consolidation.Except for only 1 case died from ARDS.The other 11 cases of this group were all haled by comprehensive treatment,and their pathological changes were absorbed.Conclusion:Chest X-y is very helpful for making the diagnosis of CMV infection after kidney transplantation.Dynamic observation is very suggestive for the prognosis.
