摘　　要：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。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 Interfascial plane involvement was manifested as thickening and lamination of the renal fascia and interfascial fluid-collection at CT. Of 37, 13, 9 and 15 were depicted as anterior interfascial plane involvement in the left, right and bilateral plane, respectively; 15 7 and 4 in the left, right and bilateral posterior interfascial plane, and 15, 6 and 3 in the left , right and bilateral lateroconal interfascial plane, 6,3 and 8 were depicted as the left, right and bilateral perirenal space involvement, respectively; and 5, 2 and 1 were depicted as left, right and bilateral posterior renal space involvement. Conclusion The anterior, posterior and lateroconal fascia could be involved in acute pancreatitis, and its anatomical basis was based on the spreading of the inflammation along the potential space within the renal fascia.
