肾前筋膜增厚在胰腺炎的CT诊断及与胰腺癌鉴别诊断中的价值

The diagnostic value of prerenal fascial thickeming in CT for pancreatitis and its significance in differentiation for pancreatic carcinoma

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 investigate the value of prerenal fascial thickening for Pancreatitis and Pancreatic careinoma in cr diagnosis. Methods: 50 ghients with Panreahtis condrmed by smpery and Pathulogy or by folowuP CT were ahalsed reprospechvely and were coinpared with CT features of 22 cases of verified panreaic careinoma.42 cases of pancreatihs and 22 carcinoma peients received plain and contrast scan while the remaining 8 pancreatitis patients underwent ouly Plain scan. ho: Derend thickening' thickening was demonstrated in 94% (47/50) paients with pancreatihs, with 97. 3 % (36/37) in acute cases and 86 .9% (11/13 ) in cboc patients whereas only two cases revealed left prerenal fascial ffockening among 22 careinom Patients (9.9% ). Conclusions: therenal fascial thickening is an important sign for CT diagnosis of pancreatitis and may help to differentiate it from pancreatitic carcinoma.
