成人肠套叠螺旋CT检查的临床意义

目的:探讨螺旋CT检查对成人肠套叠的临床意义。方法:回顾性分析12例成人肠套叠,对其CT表现及病因进行分析。结果:12例均为继发性,共有12处原发病变,其中脂肪瘤2例,淋巴瘤1例,腺瘤性息肉3例,结肠癌2例,憩室1例,血管瘤1例,慢性阑尾炎1例,平滑肌瘤1例。套叠类型:小肠套叠型5例,回回结肠型1例,回结肠型3例,结结肠型3例。12例成人肠套叠,均在套叠部发现肿块状改变,头体部呈分层状靶形肿块改变4例,肾形肿块8例,不规则肿块改变5例。套叠尾部彗星尾征改变8例。结论:成人肠套叠有特征性的CT征象,螺旋CT检查可提高成人肠套叠诊断水平,为临床选择治疗方案提供影像依据,具有重要临床意义。

Clinical significance of spiral CT in adult intussusception

Objective: To evaluate the clinical significance of spiral CT in adult intussusception. Methods: Spiral CT were performed in 12 cases of adult intussusception. The CT features and location were analyzed. Results: Twelve cases with 12 foci of intussusception were reported. All cases were secondary to primary pathology. Among them, lipoma 2 cases, adenomatous polyp 3 cases, carcinoma of colon 2 cases, diverticulum 1 case, lymphoma 1 case, angioma 1 case, chronic appendicitis 1 case, leiomyoma 1 case. The type of intussusception: small intestine-small intestine 5 cases, ileum-ileum-colon ascendens 1 case, ileum-colon ascendens 3 cases, colon-colon 3 cases. Masses were found in all of the 12 cases, including layering target masses 4 cases, kidney shape masses 8 cases, anomaly masses 5 cases, "Comet-tail" signs 8 cases. Conclusion: Adult intussusception has classic CT features, spiral CT can improve diagnostic ability of intussusception in adult, provide reliable imaging information for selecting treatment plan, has important clinical significance.
