摘要
目的分析慢性放射性肠炎(CRE)的CT表现特点。方法回顾性分析经临床确诊的27例CRE患者的临床及影像资料,分析其CT表现特征。结果 27例CRE累及直肠25例、降乙状结肠14例,回肠11例及空肠7例。CT表现肠壁增厚24例、靶征7例、肠腔狭窄5例、不全性肠梗阻7例、肠穿孔或窦道形成4例,盆腔脓肿3例。肠系膜水肿27例。其他改变包括腹腔积液7例、输尿管狭窄4例、膀胱炎4例及下肢静脉内血栓形成3例。结论 CT不仅能显示肠道本身的改变,对发现肠系膜改变、肠穿孔、盆腔脓肿及静脉血栓等方面也有明显的优势,有助于临床采取积极合理的治疗方案。
Objective To analyze CT features of chronic radiation enterocolitis Methods The clinical data and imaging materials of 27 patients with clinically confirmed chronic radiation enterocolitis were retrospectively analyzed with a focus on CT characteristics. Results In the 27 cases, the chronic radiation enterocolitis involved the rectum （n = 25）, the sigmoid colon （ n = 14）, the ileum （ n = 11 ） or the jejunum （ n = 7 ）. CT manifestations included intestinal wall thickening （ n = 24）, ＂target sign＂ （ n = 7）, narrowed intestinal canal （ n = 5 ）, incomplete intestinal obstruction （ n = 7 ）, intestinal perforation or fistula formation （ n = 4）, pelvic abscess （ n = 3 ） and edematous mesentery （ n = 27 ）. Other findings included ascites （ n = 7）, ureteral stricture （ n = 4）, cystitis （ n = 4） and thrombosis in lower extremity vein （ n = 3 ）. Conclu- sion CT can not only display the intestinal lesions, but can also demonstrate mesentery thickening, intestinal perforation, pelvic abscess and thrombosis, which are very helpful in formulating active and reasonable therapeutic scheme.
