摘　　要：目的:探讨小肠Crohn病的MSCT表现特点。方法:回顾性分析经病理证实的45例小肠Crohn病患者的MSCT征象,评价增强扫描不同期相(动脉期和门脉期)中病变肠管的强化方式及其意义。结果:45例中病变多发38例,单发7例;所有病例均出现肠壁增厚,表现为环形或偏心性增厚。增强扫描示病变段肠壁有较明显强化,呈多层状或均一强化,各种增厚及强化方式多混合存在于同一病例中;门脉期病变强化更加充分。36例合并肠系膜淋巴结肿大;13例患者出现肠系膜改变,主要表现为系膜密度升高、模糊(10例),系膜血管增生及"梳样征"(7例);21例合并肠外器官改变,包括肛周脓肿2例、腰大肌脓肿1例、骶髂关节炎1例、肾结石6例、胆囊结石及胆囊炎13例;并发瘘管穿孔1例,不全梗阻5例。结论:小肠Crohn病的MSCT表现有一定特征性,MSCT在小肠Crohn病的早期诊断及疾病发展阶段的判断中具有重要价值。Objective： To evaluate the CT features and the role of CT in the diagnosis of Crohn＇s disease. Methods：CT manifestations of 45 patients with pathology confirmed Crohn＇s disease were retrospectively analyzed. Results：All patients suffered from bowel wall thickening and contrast enhancement, various thickening and contrast enhancement multi-mode hy- brid exists in the same cases;a total of 13 cases of patients had mesenteric changes,mainly including mesangial density increases, fuzzy 10 cases and mesangial proliferative blood vessels and the ＂comb-like sign＂ change in 7 cases,36 patients with mesenteric lymph nodes;a total of 21 cases of combined parenteral organs,changes in the performance of perianal abscess in 2 cases, psoas abscess in 1 case, 1 case of sacroiliac arthritis, nephrolith in 6 cases, gallstones, cholecystitis, 13 cases ; complicated fistula perforation in 1 case, incomplete obstruction in 5 cases; dual-phase enhanced scan after the period of relative prevalence of different intestines between the comparison, the portal venous phase enhanced lesions more fully. Conclusion： Crohn＇s disease represent typical features in MSCT findings, MSCT has an important value in the early diagnosis,disease stagesing of of Crohn＇s disease.
