目的：研究肾前筋膜增厚对胰腺炎的CT诊断及与胰腺癌鉴别诊断中的价值。方法：对50例经手术病理证实或CT复查确诊胰腺炎的肾前筋膜增厚征象进行回顾性分析，并与22例手术病理证实为胰腺癌的CT表现对照。胰腺炎中42例及胰腺癌病例均做平扫加增强，余胰腺炎病例仅做平扫。结果：胰腺炎组肾前筋膜增厚发生率94％（47／50），其中急性胰腺炎肾前筋膜增厚发生率973％（36／37），慢性胰腺炎肾前筋膜发生率86.9％（11／13）。胰腺癌22例中，2例肾前筋膜增厚，占99％，均为左侧肾前筋膜。结论：在胰腺炎的诊断中，肾前筋膜增厚征象具有重要意义，并可依其改变与胰腺癌相鉴别。
Objective: To study the CT diagnosis of pancreatic inflammation and the value of prerenal fascia thickening in the differential diagnosis of pancreatic cancer. Methods: A retrospective analysis was performed on the signs of thickened anterior fascia in 50 cases confirmed by pathology or CT. The pathological findings of 22 cases were confirmed as CT findings of pancreatic cancer. Pancreatitis in 42 cases and pancreatic cancer cases were done scan and enhanced pancreatitis cases only plain scan. Results: The incidence of prerenal fascia thickening was 94% (47/50) in pancreatitis group, in which the incidence of prerenal fascia thickening in acute pancreatitis was 973% (36/37), the incidence of prerenal fascia in chronic pancreatitis 86.9% (11/13). In 22 cases of pancreatic cancer, 2 cases of prerenal fascia thickening, accounting for 99%, are left anterior fascia. Conclusion: In the diagnosis of pancreatitis, the signs of prerenal fascia thickening are of great significance and can be differentiated from pancreatic cancer according to their changes.
