胰腺癌CT征象及手术切除性估价的探讨（附67例分析）

分析了６７例经手术及病理学证实的胰腺癌的ＣＴ征象。胰腺轮廓局限性增大５０例（７４．６％），８例（１１．９％）显示向肠系膜侵犯的线条状影，等密度或均匀低密度病灶４１例（６１．２％）。受累血管以下腔静脉、肠系膜上动、静脉及腹主动脉为多（９４．８％）。脾脏增大１５例，继发假性囊肿１１例。讨论了早期胰腺癌诊断的难点和可能性，总结了胰腺癌继发囊肿的ＣＴ特征，对胰腺癌手术切除性的ＣＴ标准进行了评估。

Evaluation of CT Features and Assessment of Resectability of the Pancreatic Carcinoma:An analysis of 67 Cases

The CT features of 67 cases with pancreatic carcinoma proved pathologically were analyzed.The CT appearances of the pancreatic carcinoma were as following:Local enlargement of pancreas occurred in 50 patients(74.6%).Linear soft tissue densities extending into mesentery were found in 8 cases(11.9%)and isodense or homogeneous hypodense masses were seen in 41 cases(61.2%),According to the number of involved vessels,the order of frequency were as following:Inferior vena cava,superior mesenteric vein,superior mesenteric artery,aorta,etc.Enlarged spleens and secondary pseudocysts appeared in 15 and 11 cases respectively.Finally we discussed briefly the difficulties of the early diagnosis of pancreatic carcinoma,the CT features of the secondary pseudocysts and criteria of CT staging of pancreatic carcinoma.
