The CT Diagnosis of Cystic Type Intestinal Duplications
-
摘要: 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。Abstract: 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.
