【摘要】 目的分析类鼻疽影像表现,以提高对其认识,减少误诊。方法选择经血液、脓液及痰液培养证实的类鼻疽患者12例,均做了 X 线摄影,9例做了 CT、2例做了超声检查。结果 12例中有10例出现肺部异常,X 线胸片见两肺弥漫性片状阴影,呈部分融合;X 线胸片及 CT 均见以肺叶或肺段为单位的大片致密影,密度均匀,CT 尚可见空气支气管征;X 线胸片显示以肺门为中心,向周围肺野呈放射状分布的条状模糊影;CT 示双肺多发结节灶。X 线胸片及 CT 均显示空洞及液平,并见单或双肺散在斑片状及颗粒样影;CT 示胸腔后部弧形水样密度影等。肺外感染为眼眶、腰肌、肝脏和脾脏等部位脓肿各1例,髋关节破坏并周围脓肿1例。结论类鼻疽影像学表现尚未发现特异性征象,但可以确定病变部位、范围、程度、数量等。确诊需依赖血液、脓液及分泌物培养。更多还原

【Abstract】 Objective Imaging and clinical manifestations of melioidosis were analyzed in order to improve our understanding of the disease and to reduce the rate of misdiagnosis.Methods From 2001 to 2006,12 melioidosis cases were confirmed by blood,pus and sputum culture.All cases were examined with radiography,and nine of them with CT and 2 with US.The imaging and clinical data were assessed retrospectively.Results Ten of 12 cases revealed lung abnormalities,the main organ involved by melioidosis in the body.The appearances were observed as follows:diffused sheets and sheets fused partly in bilateral fields of the lungs can be seen on chest radiograph;homogeneous dense shadow of the lobe or segment were observed on plain chest film and CT;blurred strips radiated from hilum were revealed on plain chest film;multitude nodules in 2 lungs showed on CT;cavity with air and liquid be seen on plain chest film and CT;patches and granules in superior and middle fields or(and)inferior fields be seen on plain chest film and CT;arc shadow of water attenuation in dorsal thorax showed on CT.Infections outside the lung can be observed in orbital,lumbar muscle,liver and spleen in 1 case,and thighbone osteomyelitis with multi abscesses in one case.Conclusion Alhough medioidosis has no characteristic imaging appearances,the disease’s location,extent,severity and quantity objectively can be demonstrated by imaging,final confirmation is necessary using the culture of blood,pus and sputum.更多还原
