囊肿型肠重复畸形的CT诊断

目的：分析小儿囊肿型肠重复畸形的CT表现，以提高该病的诊断水平。方法：回顾性分析11例经手术病理证实的肠重复畸形患儿的临床资料及CT表现。结果：男8例，女3例，全部为囊肿型肠重复畸形，其中肠外型9例，肠内型2例。肠外型CT表现为单房低密度囊性肿块，囊壁较厚，增强扫描囊壁均匀强化；其中5例表现为双层状“晕轮征”。肠内型CT表现为肠腔内附壁囊性肿块，轴位扫描表现为“双弧征”。结论：囊肿型肠重复畸形临床表现缺乏特异性，CT表现较具特征性，对该病的术前诊断及鉴别诊断具有重要价值。

The CT Diagnosis of Cystic Type Intestinal Duplications

Objective： to analyze the CT manifestations of cystic type intestinal duplications and improve the diagnostic level of this disease. Methods： The clinical data of 11 cases of child cystic type intestinal duplications verified by postoperative pathologic examination were retrospectively analyzed and summarized for the CT manifestations. Results： 8 male and 3 female cases all showed cystic type intestinal duplications. 9 cases were outside the intestinal wall and 2 cases inside it. The CT manifestations abenteric cases showed a single-room low density mass, whose cystic wall was a little thick and showed an obvious homogeneous enhancement in CT scanning. 5 abenteric cases showed double-deck ＂halo sign＂. The CT manifestations of inside intestinal type showed intracavitary cystic mass attached to the intestinal wall, which manifested ＂double-arc sign＂ in the axial CT scanning. Conclusion： The clinical manifestations of cystic type intestinal duplications were not obvious, however, its CT manifestations had a few features, which showed great value in the preoperative and differential diagnosis of child cystic type intestinal duplications.
