甲状舌管囊肿的CT诊断(附15例分析)

The study on CT features of thyroglossal duct cyst(report of 15 cases)

目的 :探讨甲状舌管囊肿的CT表现及其与发病机制、病理基础的关系。方法 :分析 15例经手术和病理证实的甲状舌管囊肿的CT表现。结果 :15例中 ,9例表现为颈前正中的圆形、卵圆形或不规则形囊肿 ,6例偏向一侧。囊肿表现为低密度者 12例 ,等密度者 3例。 8例囊壁光滑 ,7例囊壁毛糙 ,10例发现囊壁内结节影。结论 :甲状舌管囊肿的特征性CT表现与其发病机制、病理基础相关。

Objective:To investigate pathogenic mechanism,pathological findings and CT features of thyroglossal duct cyst.Methods:Pathogenic mechanism,pathological findings and CT features in 15 cases with thyroglossal duct cyst defined by pathology were evaluated.Results:In CT features,9 of 15 cases were located at midline of the neck and the other 6 cases deviated aside.All thyroglossal duct cyst appeared as a round,ovary shape with saccular low density (12 cases),or isodensity mass (3 cases).In 8 cases the walls of cyst were smooth and the other 7 cases the cystic walls were coarse. In 8 cases the nodules at cystic wall were found.Conclusion:CT features of thyroglossal duct cyst were related to pathogenic mechanism and pathological findings.
