摘要
目的:探讨甲状舌管囊肿的CT表现及诊断价值。材料和方法:回顾性分析28例经CT诊断为甲状舌管囊肿病例的CT表现,并与手术和病理对照研究。结果:28例中经手术病理证实为甲状舌管囊肿25例,其CT表现为颈前正中囊肿16例,偏左侧者7例,偏右侧者2例;25例中11例位于舌骨水平,并紧贴舌骨,14例位于舌骨下方水平,其中3例紧贴甲状腺。CT平扫囊肿呈低密度15例,等密度10例。25例中24例行增强CT检查,24例囊内容物均无强化,15例囊壁光整,增强后无强化,9例囊壁毛糙,有强化,6例囊肿间见分隔影。CT诊断符合率89.3%(25/28)。结论:CT对小儿甲状舌管囊肿具有较高的定性价值。
Purpose： To study CT features of thyroglossal duct cyst（TDC） in children, Materials and Methods： 28 cases diagnosed as TDC by CT were reviewed, and compared with the surgical and pathological findings. Results： Among 28 cases, 25 cases were confirmed as TDC by surgery and pathology. 16 of the 25 cases were located at the midline, 7 cases deviated to left and 2 cases to right. 11 of the 25 cases were at the level of hyoid bone and others were under the level of the hyoid bone. 15 of the 25 cases appeared as low density, 10 of the 25 cases appeared as isodensity. 24 of the 25 cases were scanned post contrast, no enhancement was detected in the cysts, and the walls of cyst were smooth and no enhanced in 15 cases, while in 9 cases were coarse and enhanced. The accuracy rate was 89.3% （25/28）. Conclusion： CT is valuable in diagnosis of TDC in children with high accuracy.
