摘　　要：目的:探讨成人慢性肠套叠的CT表现及其临床特点,以提高对该病的认识。方法:搜集2 8例成人慢性肠套叠的病人,全部均为继发性,2 7例良性病变,其中息肉15例,平滑肌瘤6例,腺瘤2例,4例脂肪瘤;1例为腺癌。分析其CT表现及临床特点。结果:①成人慢性肠套叠临床表现不典型:病史长,可自行复位,肠壁血运障碍发生率较少;②成人慢性肠套叠CT表现为靶形肿块,肾形肿块或慧星尾征,CT发现原发病变7例。结论:成人慢性肠套叠临床表现不典型,易漏诊,CT表现有一定特征性,CT可以明确诊断,但对原发病变的发现及定性有一定的限度。Objective To study CT features and the c linical characteristics of chronic intussusception in adult.Methods Twenty eight cases with intussusception were reported.27 cases wer e benign secondary to primary pathology including polyp 15,leiomyoma 6,ad enoma 2,lipoma 4.1 case was adenocarcinoma.The clinical characteristics and CT features of these patients were analyzed.Results ① The clini cal characteristics of adult chronic intussusception were atypical clinica l manifestations.
