Teratoma of the head and neck is a rare lesion comprising 6 % of all teratomas, with only 3 % occurring in the cervical region [1]. Most are non-malignant lesions consisting of a variety of tissues of variable maturity, commonly with neuroepithelial and thyroid elements. They often present as a large cystic mass in the neck of a neonate or infant and frequently cause respiratory embarrassment due to local mass effect necessitating urgent surgical intervention. They may be difficult to distinguish from cystic hygromas, both clinically and radiologically. Imaging plays an important role in the assessment of these lesions, especially in preparation for surgery. We present a case of cervical teratoma and emphasise the role of MRI.
头颈部畸胎瘤是一种罕见的病变，占所有畸胎瘤的6%，仅3%发生在颈部区域[1]。大多数是非恶性病变，由各种成熟度不同的组织组成，通常含有神经上皮和甲状腺成分。它们常表现为新生儿或婴儿颈部的巨大囊性肿块，由于局部肿块效应常导致呼吸窘迫，需要紧急手术干预。在临床和放射学上，它们可能难以与淋巴管瘤区分。影像学在这些病变的评估中起着重要作用，尤其是在手术准备方面。我们报告一例颈部畸胎瘤病例，并强调MRI的作用。
