摘　　要：目的探讨肠系膜脂膜炎多层螺旋CT的诊断价值。方法总结21例经临床及影像诊断证实的肠系膜脂膜炎的多层螺旋CT影像资料,其中手术证实2例,依据CT诊断标准诊断19例。采用CT平扫9例,平扫及增强12例。1例行MRI平扫及增强扫描。结果 21例病例中,12例发病部位起自小肠系膜根部,其余9例病变位于小肠系膜中上部。表现为肠系膜"脂肪晕环"征16例;"假包膜征"7例;肠系膜多发结节2例;7例表现为肠系膜血管周围局限或广泛的云絮状密度增高影;2例出现肠袢移位,无肠管受浸润病例;2例病变内可见小结节状钙化。结论肠系膜脂膜炎无特征性临床表现。多层螺旋CT检查有助于肠系膜脂膜炎的诊断。Objective To discuss the value of the multislice helical CT（MSCT） for the diagnosis of mesenteric panniculitis. Methods In this study, the MSCT images of 21 cases with mesenteric panniculitis were analyzed retrospectively, in which, the diagnosis of 2 cases was confirmed by histopathology. The rest cases were diagnosed based on the CT criteria. Among 21 cases, 9 had plain scan. The others had both plain and enhanced scan. One case had MRI examination. Results Among the 21 cases, the panniculitis of 12 started from the root of the small bowel mesentery. The disorder started of 9 cases started from the superior and middle parts of the small bowel mesentery. Sixteen cases had ＂fat ring＂ sign; 7 cases manifested as pseudo-encapsulated mass; 2 cases presented as multinodularpattern; 7cases showed patching shadows in the mesentery; 2 cases had intestinal loop changed but no infiltration; 2 cases had small amount of calcification. Conclusion As mesenteric panniculitis have no distinctive clinical manifestations, MSCT is very helpful to make a definite diagnosis.
