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.
