硬化性肠系膜炎多层螺旋CT诊断的价值

目的探讨硬化性肠系膜炎的多层螺旋CT表现及其诊断价值。方法回顾性分析13例硬化性肠系膜炎患者的完整的临床资料及多层螺旋CT资料，其中7例行平扫及增强扫描，6例平扫，所有图像均行多平面重组（MPR）及最大密度投影（MIP）重建后分析。结果13例SM病变均起自肠系膜根部，且包绕肠系膜血管，有明显占位效应，平均大小约45mm×113mm，平扫呈雾状系膜，增强后强化不明显，9例有假包膜，6例肿块内可见血管周围脂肪环征。结论多层螺旋CT是诊断硬化性肠系膜炎的首选工具之一，有非常重要的价值。

The value of multislice helical CT in diagnosis of sclerosing mesenteritis

Objective To evaluate the manifestations of sclerosing mesenteritis demonstrated by multislice helical CT.Methods The full clinic and multislice helical CT data of 13 patients with sclerosing mesenteritis were analyzed retrospectively in this study.7 patients underwent both contrast enhancement and plain CT scan while 6 patients only underwent plain ct scan.All scan data were investigated after maximum intensity projection (MIP) and multiplanar reconstruction (MPR).Rseults The lesion of all 13 cases,which surround mesenteric arteries,originated from mesenteric root and showed significant mass effect.The average size was about 45 mm×113 mm.A mist-like mesentery sign was demonstrated in plain CT scan,and no enhancement was found after contrast media injected.9 of 13 cases had pseudocapsule.6 of 13 cases showed fatty.Conclusion Multislice helical CT is very useful for detecting sclerosing mesenteritis,and it play an important role in diagnosis and treatment of sclerosing msenteritis.
