【摘要】 目的 总结结肠多发憩室的多层螺旋CT(MSCT)表现，提高MSCT对结肠多发憩室的诊断水平。方法 回顾性分析30例经结肠镜证实的结肠多发憩室临床及CT资料，总结其CT特征并与结肠镜表现相对照。结果 30例经内镜证实结肠多发憩室患者中，发生于升结肠16例，降结肠6例，乙状结肠5例，横结肠1例，全结肠2例；5例提示憩室黏膜炎。19例患者MSCT表现为多发突出于肠壁小囊袋状突起(阳性率63.3%,19/30),直径约3.0～10.0 mm,多发小囊状突起内单纯含有气体或液体11例，小粪石充填8例；5例病变肠管周围脂肪间隙模糊；11例病变肠管无明显影像学异常。结论 结肠多发憩室较为可靠的MSCT表现为多发突出于结肠壁外的小囊状突起，内容物可以是气体、液体及小粪石，直径多<1 cm;当多发憩室肠管周围脂肪间隙模糊时，常提示合并憩室炎。更多还原

【Abstract】 Objective To discuss MSCT signs of colon multiple diverticulum in order to improve the accuracy of diagnosis.Methods MSCT signs and clinical data of 30 cases with colon multiple diverticulum of were analyzed retrospectively.Imaging characteristics of colon multiple diverticulum were summarized and comparated with the results of colonoscopic appearance.Results There were 30 cases of colon multiple diverticulum confirmed by colonoscopy,including 16 cases in the ascending colon,6 cases the descending colon,5 cases the sigmoid colon,1 case transverse colon,2 cases the whole colon,5 cases with diverticulitis.Multiple projecting processes were showed in 19 cases(63.3%,19/30),lesion diameter were 3.0-10.0 mm,gas or liquid filled in the lesion in11 cases,small bezoar filled in 8 cases and the surrounding fat gaps were fuzzy in 5 cases.There was no any MSCT abnormal sign in11 cases.Conclusion The typical MSCT signs of colon multiple diverticulum are multiple projecting processes,which size is smaller than 1 cm and filled with gas,liquid or small bezoar.The sign of surrounding fat gap fuzzy often means diverticulitis.更多还原
