摘　　要：目的：分析老年性结肠多发憩室的多层螺旋CT表现，提高对老年性结肠多发憩室认识。方法：搜集40例结肠镜证实的老年性结肠多发憩室临床及CT资料，总结MSCT特征并与结肠镜表现相对照。结果：40例老年性结肠多发憩室患者中，发生于升结肠的21例，降结肠11例，乙状结肠5例，横结肠1例，全结肠2例。8例提示憩室黏膜炎。老年性结肠多发憩室的MSCT表现为多发、突出于肠壁轮廓外的小囊袋状突起，直径3．0～10．0mm，小囊袋状突起内容物为气体16例，液体11例，粪石13例；6例病变肠管周围脂肪间隙模糊。结论：老年性结肠多发憩室多层螺旋CT直接征象为多发、突出于肠轮廓外的囊带状突起，直径多小于1cm，受累肠管周围脂肪间隙模糊可提示合并憩室炎。Objective： To discuss the MSCT features of senile colon multiple diverticula, in order to improve the knowledge of the disease entity. Methods：The clinical and MSCT materials of forty patients with senile multiple colon diverticula proved by colonoscopy were collected and the CT features were correlated with colonoscopy appearances. Results： Of the 40 patients with senile multiple colon diverticula, the location was ascending colon （21 patients）, descending colon （11 patients） ,sigmoid colon （5 patients）,transverse colon （one patient） and all segments of colon （2 patients）. Eight patients had diverticulitis. The MSCT features of senile colon multiple diverticula were multiple small sac-like protrusions bulged outside of the bowel wall, with the diameter ranged from 3.0mm to 10.0mm, gas （16 patients）, liquid （11 patients） and small bezoar （13 patients） were showed within the small sac-like protrusions. Fuzzy peri-colonal fat space was assessed in 6 patients. Conclusion：The direct MSCT features of senile multiple colon diverticula are multiple small sac like protrusions with the diameter less than lcm outside of the colon wall. Associated diverticulitis is suggested when peri-colonal fuzzy fatty inter-space is showed.
