小儿甲状舌管囊肿的超声特点

目的分析小儿甲状舌管囊肿的超声图像特征及其对该疾病的诊断价值。方法对38例病理确诊为甲状舌管囊肿的小儿超声图像进行回顾性分析和总结。评估超声图像中甲状舌管囊肿的位置,形态,内部回声类型,有无内隔,囊肿壁厚,后回声增强,实质成分,囊肿边界和瘘管的存在情况。结果多数甲状舌管囊肿居于颈部中线(30例),位于舌骨(18例)或舌骨下(14例),31例囊肿有后方回声增强,33例为单房,34例没有内隔存在,28例有一层薄壁。所有病例均未发现实质成分。内回声可分为3型:无回声(11例),均一低回声(9例),不均一回声(18例)。10例厚壁患者中,8例有炎症;4例存在内隔的患者中也均发现炎症。结论多数儿童甲状舌管囊肿位于中线,舌骨或舌骨下水平,单房薄壁,并有后回声增强。多数囊肿为低回声或不均一回声。厚壁和内隔的存在提示炎症的发生。仔细评估甲状舌管囊肿的超声图像有助于做出准确的术前诊断。

Ultrasonic Diagnosis of Thyroglossal Duct Cyst in Children

Objective The purpose of this study was to analyze the sonographic features of thyroglossal duct cysts(TDCs) in children and its diagnostic value.Methods We analyzed and summarized the sonograms from 38 children with pathologically proven TDCs retrospectively.The lesions were evaluated for location,shape,internal echo pattern,internal septa,wall thickness,posterior enhancement,solid components,margins,and fistulas.Results Most TDCs were at midline(30 cases),located at the hyoid bone(18 cases) or were infrah...
