青海地区泡型肝包虫病多脏器转移的磁共振成象诊断与鉴别

目的 探讨青海地区泡型肝包虫病合并多脏器转移的磁共振成象(MRI)表现特点及鉴别诊断.方法 回顾性分析2008年1月～2012年1月某院收治的100例经手术后病理检查确诊为泡型肝包虫病患者的临床及影像学资料,总结分析泡型肝包虫病脑、肺、肾等部位转移的MRI特点.结果 ①本组100例泡型肝包虫病患者中,其中位于左叶者占27.0％ (27/100),位于右叶者占57.0％ (57/100),左右叶均受累者占16.0％ (16/100),位于右叶者所占比例高于左叶和两叶均受累者,比较差异有统计学意义(P＜0.05).②100例患者中并发脑转移13例(13.0％),双肺转移17例(17.0％),脑和双肺转移19例(19.0％),脑和肾转移15例(15.0％)以及脑、肺、肾等多脏器转移者11例(11.0％),各部位所占比例比较差异无统计学意义(P＞ 0.05).结论 MRI检查可显示泡型肝包虫的数目、大小和形态、囊壁、子囊、钙化以及与周边器官的的解剖关系,还可以提示病程变化,有助于临床鉴别诊断.

MRI diagnosis and differential diagnosis of multiple organ metastasis of liver echinococcosis in Qinghai

OBJECTIVE To study the MRI diagnosis and differential diagnosis of multiple organ metastasis of liver echinococcosis in Qinghai.METHODS From January 2008 to January 2012,100 cases with liver echinococcosis diagnosised by postoperative histopathologic examination were retrospective analyzed,and the MRI characteristics of multiple organ metastasis were summarized and analyzed including brain,lung,kidney and other organs.RESULTS ① In the 100 cases,the left lobe was 27.0%(27/100),the right lobe was 57.0%(57/100),and around the liver was 16.0%(16/100),and the proportion of the right lobe was higher than the others with statistical significance(P﹤0.05).② In 100 cases,the brain metastasis was 13 cases(13.0%),double lung metastases was 17 cases(17.0%),the brain and the double lung metastases was 19 cases(19.0%),brain and kidney metastasis was 15 cases(15.0%)and brain,lung,kidney and other much viscera metastasis was 11 patients(11.0%),and the proportions had no significant differences(P﹥0.05).CONCLUSION MRI examination can show the number,size and shape of liver hydatid,bursa wall,ascus,calcification and the surrounding organs,which was contributed to the clinical differential diagnosis.
