急性胰腺炎累及肾筋膜间平面的螺旋CT表现及其解剖学基础

目的探讨急性胰腺炎累及肾筋膜间平面的螺旋CT表现及其解剖学基础。方法回顾性分析37例经病理和（或）临床及实验室检查证实为急性胰腺炎患者的完备的CT图像资料。观察项目主要包括：胰腺实质形态、密度、强化特征、有无坏死;胰腺周围积液情况;双侧肾前筋膜间平面、肾后筋膜间平面、锥侧筋膜间平面受累的情况;肾周间隙及肾旁后间隙受累的影像表现。结果肾筋膜间平面受累表现为肾筋膜增厚、分层及筋膜间积液。左侧、右侧和双侧肾前筋膜间平面受累分别为13、9和15例。左侧、右侧和双侧肾后筋膜间平面受累分别为15、7、4例。左、右侧和双侧锥侧筋膜间平面受累分别为15、6、3例。左侧、右侧和双侧肾周间隙受累分别为6、3、8例。左侧、右侧、双侧肾旁后间隙受累分别为5、2、1例。结论急性胰腺炎可累及双侧肾前、肾后及锥侧筋膜间平面,炎症在筋膜间存在的潜在间隙内蔓延是其影像学表现的解剖学基础。

Involvement of renal interfasicial plane in acute pancreatitis: spiral CT features and the anatomical basis

Objective To explore the spiral CT features and the anatomical basis of renal interfascial plane involvement in acute pancreatitis. Methods CT images of 37 patients with acute pancreatitis confirmed pathologically or clinically were retrospectively reviewed. Imaging interpretation included the morphology, density, enhancement of the affected pancreas, peripancreatiic fluid collection; involvement of bilateral interfascial plane and the perirenal space and posterior pararenal space. Results Renal Interfascia...
