顽固发作性胰腺炎与胰腺癌的临床CT征象鉴别性探究

Clinical CT signs identification of intractable seizures pancreatitis and pancreatic cancer

目的探讨顽固发作性胰腺炎与胰腺癌的临床CT征象鉴别诊断。方法回顾性分析胰腺癌患者30例以及顽固发作性胰腺炎患者30例的临床资料和CT影像资料,分析临床CT征象特征。结果胰腺CT影像学结果显示,两组胰腺密度异常、胰管扩张比例无显著差异(P>0.05);胰腺癌主要表现为胰腺局限性增大,反复发作胰腺炎组主要表现为胰腺弥漫性增大,差异有统计学意义(P<0.01);胰腺癌组有1例为扩张胰管贯通区病变,而反复发作胰腺炎组有11例为扩张胰管贯通区病变,差异有高度统计学意义(P<0.01)。胰腺癌组CT强化结果主要表现为肿块或者结节状持续性弱强化,而反复发作胰腺炎组主要表现为非肿块型不均匀性强化,差异有统计学意义(P<0.01)。结论胰腺癌与顽固性反复发作胰腺炎在CT影像学上各有特点,尤其是增强扫描,能够为两者的鉴别提供依据。

Objective To discuss clinical CT signs identification of intractable seizures pancreatitis and pancreatic cancer. Methods Clinical and CT signs of 30 cases with pancreatic cancer and 30 cases with intractable seizures pan-creatitis were respectively analyzed. Clinical and CT signs were analyzed. Results CT imaging of the pancreas showed,abnormal pancreas, pancreatic duct dilatation proportion of two group showed no significant difference（P〉0.05）; The performance of pancreatic cancer CT signs showed the volume of the pancreas increased limitedly, and the volume of the intractable seizures pancreatitis increased widespread（P〈0.01）;there was one case of pancreatic cancer through the pancreatic duct dilatation lesions,but 11 cases of intractable seizures pancreatitis group（P〈0.01）. CT enhancement re-sults showed that, pancreatic cancer group was lumps or nodules continued weak strengthening, and intractable seizures pancreatitis was non-mass type heterogeneous enhancement （P〈0.01）. Conclusion CT signs of intractable seizures pancreatitis and pancreatic cancer are different. Especially enhanced scan can provide the basis for the identi-fication of the two.
