The purpose of this study was to identify ultrasonographic features that can be used to differentiate between thyroglossal duct cysts (TGDCs) and dermoid cysts (DCs).
We searched surgical pathology reports completed between January 2004 and October 2015 and identified 66 patients with TGDCs or DCs who had undergone preoperative ultrasonography. The ultrasound images were reviewed by two radiologists who were blinded to the pathological diagnosis. They evaluated the following parameters: dimensions, shape, margin, location in relation to the midline, level in relation to the hyoid bone, attachment to the hyoid bone, the depth of the lesion in relation to the strap muscles, internal echogenicity, internal echogenic dots, multilocularity, the presence of a longitudinal extension into the tongue base, posterior acoustic enhancement, the presence of internal septae, and intralesional vascularity.
There were 50 TGDCs and 16 DCs. TGDCs were significantly more likely than DCs to have an irregular shape, an ill-defined margin, attachment to the hyoid bone, an intramuscular location, heterogeneous internal echogenicity, multilocularity, and longitudinal extension into the tongue base.
Ultrasound findings may inform the differential diagnosis between TGDCs and DCs.
本研究旨在确定可用于鉴别甲状舌管囊肿（TGDCs）和皮样囊肿（DCs）的超声特征。
我们检索了2004年1月至2015年10月期间完成的手术病理报告，确定了66例接受过术前超声检查的TGDCs或DCs患者。两名对病理诊断不知情的放射科医生对超声图像进行了回顾。他们评估了以下参数：尺寸、形状、边缘、相对于中线的位置、相对于舌骨的水平、与舌骨的附着情况、病变相对于带状肌的深度、内部回声、内部回声点、多房性、向舌根的纵向延伸情况、后方回声增强、内部间隔的存在以及病变内血管情况。
有50例TGDCs和16例DCs。TGDCs比DCs更有可能具有不规则形状、边界不清、与舌骨附着、肌内位置、内部回声不均匀、多房性以及向舌根的纵向延伸。
超声检查结果可为TGDCs和DCs的鉴别诊断提供依据。
