类鼻疽肝脓肿的CT表现(附2例报告并文献复习)

CT Findings of Pseudomonas Pseudomallei Liver Abscess: A Report of 2 Cases with A Review of Literature

目的 提高对类鼻疽肝脓肿CT表现的认识。资料与方法 经血培养和类鼻疽抗体检查证实的类鼻疽肝脓肿患者 2例 ,均行腹部CT检查。结果 类鼻疽肝脓肿的CT表现有以下特点 :肝内多发小脓肿聚集成蜂窝状 ,小脓腔直径约 2～ 3mm ,常伴有多发脾脓肿。结论 类鼻疽肝脓肿确诊一般依赖病原体鉴定 ,但出现CT高度怀疑的征象对早期诊断有重要的临床意义。

Objective To make a further understanding of CT sings of pseudomonas pseudomallei liver abscess. Materials and Methods Two cases of pseudomonas pseudomallei liver abscess, proved with bacteriologic culture and serum antibody test, underwent abdominal CT scanning. CT findings were observed and analyzed.Results Characteristic CT manifestations of pseudomonas pseudomallei liver abscess were intrahepatic multiple 2～3mm-sized microabscesses, which assembled in honeycomb appearance, multiple splenic abscesses were usually accompanied.Conclusion The confirmation of the diagnosis of pseudomonas pseudomallei liver abscess usually depends on the identification of the specific pathogen. The characteristic CT signs are very suggestive for making an early diagnosis.
