肾移植后巨细胞病毒肺炎的X线和CT表现

The X-ray and CT Appearances of Cytomegalovirus Pneumonitis after Kidney Transplant

目的 :提高X线胸片和CT诊断肾移植后巨细胞病毒 (CMV)肺炎的水平。材料和方法 :回顾性分析 11例肾移植后CMV患者的X线胸片和CT表现。结果 :肾移植后CMV肺炎 8例X线胸片表现为磨玻璃影和实变影 ,3例胸片正常 ;CT表现为双肺弥漫性病变 ,磨玻璃影最为常见 ,并与其它影像学表现合并存在 ,主要与实变影和多发性小结节样影合并存在 ;磨玻璃影在所有患者均表现为两侧肺分布。 10例患者有多发性小结节样影 ;8例患者有多发实变影 ;5例并发有少量胸腔积液和小叶间隔增厚。结论 :肾移植后CMV肺炎的CT表现有一定特点 ,结合临床可提示诊断。

Purpose: To improve chest radigrcophic and CT diagnosis in cytomegalovirus pneumonia after kidney transplant. Materials and Methods: The chest radiogrqphic and CT appearances of 11 patients with cytomegalovirus prceumonitis after kidney transplomt were retrospectively analysed. Results: Bilateral ground-glass opacity and consolidation on the chest X-ray films were seen in 8 patients, and the chest X-ray films were normal in 3 patients. Bilateral abnormalities on CT scans were seen in all patients. The most frequent CT appearance was ground-glass opacity, seen in all patients. It was mixed with other patterns, mainly areas of small nodules and consolidation. The areas of ground-glass opacity were distributed bilaterally in all patients. Small nodules were seen in 10 patients. The area of consolidation was bilateral in 8 patients. Bilateral areas of thickened interlobular septa were present in 5 patients. Pleural effusion was seen in 5 patients. Conclusion: The CT manifestations of cytomegalovirus pneumonitis after kidney transplant have some characteristics,associated with clinic data, can suggest the diagnosis of cytomegalovirus prenoronitis.
