摘要
目的分析小儿肠重复畸形的 CT 表现特征，探讨其诊断价值。方法回顾性分析经手术及病理检查证实的小儿肠重复畸形22例，分析其 CT 表现特点。结果22例肠重复畸形中，发生在十二指肠1例，空肠2例，回肠11例，回盲部6例，结肠2例。病理类型：肠外囊肿型18例，肠内囊肿型2例，肠外管状型2例。CT 平扫均表现为囊性肿块，22例中20例囊壁较厚，增强扫描囊壁均有强化，CT表现特征为圆形、椭圆形或管形、单房、液性低密度、厚壁囊肿。术前 CT 诊断14例，误诊6例，漏诊2例，符合率为63．6％。其中9例有其他合并症，4例并发不全性肠梗阻，2例并发感染与周围组织粘连，2例并发肠套叠，1例并发囊内出血。结论小儿肠重复畸形常常合并急腹症发病，容易误诊、漏诊。CT表现具有一定的特征性，可作为本病定位、定性诊断的重要影像学手段。
Objetive To evaluate CT diagnosis of intestinal duplication in children.Methods A retro-spective review was made on the CT findings of 22 cases with intestinal duplication proved by pathology. Re-sults Among the 22 cases,duplication was found in duodenum in 1 case,jejunum in 2 cases,ileum in 11 ca-ses,ileocecus in 6 cases,and colon in 2 cases.There were three pathologic types,including extraintestinal cyst-ic type （18 cases）,intraintestinal cystic type （2 cases）,extraintestinal tubular type （2 cases）.On CT scan, the lesion presented as low-density and unilocular cyst,and 20 out of the total 22 cases were found with thick cystic wall which was enhanced after contrast injection.Fluid Low-density unilocular cyst,round or tubular shape,thickened wall are the typical CT findings of intestinal duplication,14 cases were diagnosed correctly with a correspondent rate of 63.6%,and 6 cases were misdiagnosed,2 cases missed diagnosis.9 cases presen-ted as complication,inlcuding incomplete obstruction in 4 cases,inflammation with adhesion to adjacent struc-tures in 2 cases,intussusception in 2 cases,and intracavitary hemorrhage in 1 case. Conclusion Intestinal du-plication in children often present as acute abdomen,and is very likely to be misdiagnosed.CT manifestations are quite characterized,thus it is very helpful for the diagnosis of intestinal duplication.
