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。
Objective To discuss MSCT signs of colon multiple diverticulum in order to improve the accuracy of diagnosis.Meth-ods MSCT signs and clinical data of 30 cases with colon multiple diverticulum of were analyzed retrospectively.Imaging character-istics 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 1 6 cases in the ascending colon,6 cases the de-scending colon,5 cases the sigmoid colon,1 case transverse colon,2 cases the whole colon,5 cases with diverticulitis.Multiple pro-jecting processes were showed in 1 9 cases(63.3%,1 9/30),lesion diameter were 3.0-10.0 mm,gas or liquid filled in the lesion in 1 1 cases,small bezoar filled in 8 cases and the surrounding fat gaps were fuzzy in 5 cases.There was no any MSCT abnormal sign in 1 1 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.
