中文摘要：

目的：对急性肠脂垂炎的CT征象加以分析,旨在提高对该病的认识。材料与方法 ：搜集2009年—2012年间由CT检查及之后随访诊断为肠脂垂炎的24例患者的临床及影像学资料,分析肠脂垂炎发生的位置,病变的大小、形态、密度、周围炎性反应、邻近肠壁改变等。结果：24例患者的肠脂垂炎均为单发,表现为紧邻肠壁的圆形或类圆形病灶,边缘呈完整或不完整环形软组织密度,中心呈脂肪密度。100%的病灶周围见到模糊渗出影,局部肠壁均未见明显增厚,17例病变邻近腹膜可见不同程度增厚、渗出。结论：肠脂垂炎具有一定的临床及影像特征,正确的诊断将有助于避免该病的过度治疗。

英文摘要：

Objective： To study the imaging features of epiploic appendagitis. Methods and Materials： Clinical and imaging data of 24 patients diagnosed as epiploic appendagitis from 2009 to 2012 were studied retrospectively. Location, size,shape, density, surrounding inflammation and change of adjacent bowel wall were analyzed. Results： All of the lesions were solitary, appearing as round or oval lesions abutting colon wall, with density of fat inside and density of soft tissue of the border. Inflammatory infiltration was seen around all of the lesions, but no thickening of adjacent bowel wall was found. Thickening and exudation of adjacent peritoneum was seen in 17 cases. Conclusion： Characteristic clinical and CT features of epiploic appendagitis can help to avoid incorrect treatment.
