Thyroglossal duct cyst is the most common congenital neck mass in children and young adults. The authors present two cases affecting two patients aged 7 and 9 years, respectively, who had a palpable painless swelling in the submental region. In both patients ultrasound (US) examination showed an anechoic or hypoechoic rounded mass with well-defined margins thus confirming clinical suspicion of thyroglossal duct cyst. One patient also had a second, deep-lying, nonpalpaple cyst which communicated with the superficial cyst. These cases are typical and confirm that US is essential in suspected thyroglossal duct cyst to confirm clinical diagnosis, detect lesions which are not clinically appreciable due to their small size or deep location, to assess communication between the lesions and to detect possible complications.

甲状舌管囊肿是儿童和青年中最常见的先天性颈部肿块。作者报告了两例分别影响7岁和9岁患者的病例，这两名患者在颏下区域均有可触及的无痛性肿胀。两名患者的超声（US）检查均显示出一个无回声或低回声的圆形肿块，边界清晰，从而证实了临床对甲状舌管囊肿的怀疑。其中一名患者还存在第二个位于深部、不可触及的囊肿，该囊肿与浅表囊肿相通。这些病例具有典型性，证实了在疑似甲状舌管囊肿时，超声对于确认临床诊断、检测因体积小或位置深而临床上不易察觉的病变、评估病变之间的连通性以及检测可能的并发症至关重要。甲状舌管囊肿是儿童和青年中最常见的先天性颈部肿块。作者报告了两例分别影响7岁和9岁患者的病例，这两名患者在颏下区域均有可触及的无痛性肿胀。两名患者的超声（US）检查均显示出一个无回声或低回声的圆形肿块，边界清晰，从而证实了临床对甲状舌管囊肿的怀疑。其中一名患者还存在第二个位于深部、不可触及的囊肿，该囊肿与浅表囊肿相通。这些病例具有典型性，证实了在疑似甲状舌管囊肿时，超声对于确认临床诊断、检测因体积小或位置深而临床上不易察觉的病变、评估病变之间的连通性以及检测可能的并发症至关重要。
