摘    要:目的:胰腺癌胰周淋巴结转移的分布特征及螺旋CT影像表现。方法:搜集经手术病理诊断为原发性胰腺癌45例,所有病例均经手术病理或影像标准诊断有胰周淋巴结转移。根据本组45例病例CT所反映的肿大淋巴结的分布情况,将胰周淋巴结分为8组。设定淋巴结的短径≥1.0cm为淋巴结转移阳性的影像表现。统计阳性淋巴结的出现率,重点观察淋巴结转移的部位、大小、数目、形态、密度、强化情况。结果:本组45例胰腺癌中,共计89个部位观察到淋巴结转移胰周转移淋巴结以腹腔动脉干组46.7%(21例),肠系膜根部组46.7%(21例),腹主动脉周围组35.6%(16例)为最多,胃周11.1%(5例)及脾动脉-脾门组13.3%(6例)最少。结论:胰腺癌转移所致肿大淋巴结主要分布在腹腔干、肠系膜根部以及腹主动脉周围。螺旋CT扫描检查可以较准确显示胰腺癌胰周淋巴结的转移情况。

Abstract:Objective:To evaluate the CT feature and distribution characteristics of metastases in patients with pancreatic carcinoma.Methods:Forty-five histopathologically or CT imaging criteria (maximum short axis diameter of lymph node equal to or larger than 10mm) proven cases of pancreatic carcinoma with peripancreatic lymph node metastases were included in our study.According to the lymph node location,peripancreatic lymph node were classified as eight groups.CT imaging was evaluated with special attention to the size,number,shape,density,enhancement and anatomic distribution of peripancreatic lymph node metastases.Results:The peripancreatic lymph node metastases were mainly observed around the celiac trunk (46.7%) and superior mesenteric vessels (46.7%),and at para- aortic area (35.6%).Conclusion:The anatomic distribution which closely reflects the lymphatic spreading pathways of pancreatic carcinoma of peripancreatic lymph node metastases are mainly located around the celiac trunk,superior mesenteric vessels and at paraaortic area.CT imaging can clearly reveal the location of lymphadenopathy in patients with pancreatic carcinoma.
Keywords:Pancreatic carcinoma  Metastasis  Lymph nodes  Tomography  X-ray computed
