多层螺旋CT对儿童肠重复畸形的诊断价值

Value of MSCT in the Diagnosis of Children's Intestinal Duplication

目的探讨多层螺旋CT对儿童肠重复畸形的诊断价值。方法回顾性分析20例经手术病理证实的肠重复畸形CT表现。结果本组20例肠重复畸形中,位于胃底部1例,十二指肠2例,空肠1例,回肠13例,升结肠及降结肠各1例,膀胱1例。19例病变位于肠系膜侧,1例位于系膜对侧。1例病变与升结肠间可见细蒂相连呈憩室型改变,1例与降结肠伴行呈管状,余18例均为囊肿型。1例合并畸胎瘤,1例合并肠套叠,3例合并肠扭转。结论多层螺旋CT具有较高的密度分辨力,结合后处理三重建技术,可对儿童肠重复畸形的诊断提供重要信息。

Objective To explore value of multi-slice CT （MSCT） in the diagnosis of children＇ s intestinal duplication. Methods The imaging features and clinical materials of 20 cases with pathologically confirmed intestinal duplication were retrospectively analyzed. Results Among 20 cases of intestinal duplication, 1 case located in the bottom of the stomach, 2 cases in duodenum, 1 case in jejunum, 13 cases in ileum, 1 case in ascending colon and descending colon respectively, and I case in bladder; 19 cases located in the mesenteric side, and only 1 case located in the contralateral of mesentery; 1 case connected with ascending colon and presented as diverticulum type, 1 case connected with descending colon and presented as tubular type, other 18 cases presented as cyst type： 1 case combined with teratoma, 1 case with intussusception, and 3 cases with volvulus. Conclusion MSCT has high density resolution. It could provide important informacion in the diagnosis of-children＇ s intestinal duplication combined with post-processing three dimensional recoustruction.
