Thyroglossal duct cyst (TGDC) is a congenital neck malformation, with a rate of approximately 7% in paediatric patients. TGDC is rarely detected in infants aged younger than 1 year. Even though TGDC is histologically benign, it is associated with preterm delivery or sudden infant death due to airway obstruction, with a mortality rate of 30% to 40%. We report a rare case of a neonate who presented with a large left lateral neck mass. At 7 to 8 months of gestation, magnetic resonance imaging of the foetal neck showed that there was a high possibility of a cervical cystic lymphangioma. The patient had normal vital signs and was afebrile. She was immediately transferred to our Ear, Nose, and Throat Department for further diagnosis and treatment. A computed tomography scan confirmed a large cystic mass that was positioned against a thyroglossal duct. Excision of the mass in the left neck was performed under general anaesthesia without resecting part of the hyoid bone. A histopathological examination confirmed the diagnosis of a TGDC. Follow-up at 1 year showed no recurrence.
甲状舌管囊肿（TGDC）是一种先天性颈部畸形，在儿科患者中的发生率约为7%。1岁以下婴儿很少检测到TGDC。尽管TGDC在组织学上是良性的，但它与早产或因气道阻塞导致的婴儿猝死有关，死亡率为30%至40%。我们报告了一例罕见的新生儿病例，该新生儿左侧颈部出现巨大肿块。在妊娠7至8个月时，胎儿颈部的磁共振成像显示有很大可能是颈部囊性淋巴管瘤。该患者生命体征正常，无发热。她立即被转至我们的耳鼻喉科进行进一步诊断和治疗。计算机断层扫描证实有一个巨大的囊性肿块，位于甲状舌管处附近。在全身麻醉下对左侧颈部肿块进行了切除，未切除部分舌骨。组织病理学检查确诊为TGDC。1年的随访显示无复发。
