Cystic lesions related to the upper airway are an unusual cause of infantile stridor. Such a lesion may exert a mass effect, with subsequent airway compromise.
A six-month-old boy was transferred to our unit with a right-sided, level IV neck lump and a three-month history of chronic cough and, latterly, inspiratory stridor. Computed tomography revealed a large, unilocular, cystic, cervicothoracic lesion causing marked compression of the trachea. Airway endoscopy subsequently revealed the larynx to be displaced to the left, with severe external compression of the trachea from just below the subglottic level to immediately above the carina. The mediastinal lesion was excised via an external approach. The histological diagnosis was a bronchogenic cyst.
Bronchogenic cysts are a rare cause of infantile stridor, and should be considered in the differential diagnosis of cystic cervical and mediastinal masses. Surgical excision is the treatment of choice.
与上呼吸道相关的囊性病变是婴儿喘鸣的罕见原因。此类病变可能产生占位效应，继而导致气道受压。
一名6个月大的男婴因右侧IV级颈部肿块以及3个月的慢性咳嗽病史，近期出现吸气性喘鸣而转入我院。计算机断层扫描显示，一个巨大的、单房性的、囊性的颈胸段病变对气管造成了明显压迫。气道内镜检查随后发现喉部向左移位，气管从声门下水平稍下方至隆突上方受到严重外部压迫。通过外部入路切除了纵隔病变。组织学诊断为支气管源性囊肿。
支气管源性囊肿是婴儿喘鸣的罕见原因，在鉴别诊断颈部和纵隔囊性肿块时应予以考虑。手术切除是首选治疗方法。
