Cervical thymic cysts (CTCs) are unusual lesions, representing only 1% of cystic cervical masses. Diagnosis of this condition in adults is even rarer. We report a 34-year-old female who presented with asymptomatic progressively growing left-sided neck swelling. Neck ultrasound (US) showed a large cystic lesion with septation, compressing the ipsilateral vessels. Magnetic resonance imaging (MRI) confirmed the US findings. Surgical excision was performed which subsequently showed findings consistent with CTC. CTC in adult is extremely rare, with few reported cases identified in the literature. Thymic gland anomalies in the neck are the consequences of an arrest in the descent of the gland, sequestration of the thymic tissue, or failure of involution. The diagnosis of this condition is rarely done prior to surgical excision. The clinical presentation, radiologic imaging, surgical findings, and histologic appearance are all essential components to make the correct diagnosis of this very rare differential diagnosis of cystic lateral neck swelling.
颈胸腺囊肿（CTCs）是一种罕见的病变，仅占颈部囊性肿块的1%。在成人中诊断出这种疾病更为罕见。我们报告一名34岁女性，她出现左侧颈部无症状且逐渐增大的肿胀。颈部超声（US）显示一个有分隔的大囊性病变，压迫同侧血管。磁共振成像（MRI）证实了超声检查结果。进行了手术切除，随后显示的结果与颈胸腺囊肿一致。成人颈胸腺囊肿极为罕见，文献中报道的病例很少。颈部胸腺异常是胸腺下降受阻、胸腺组织隔离或退化失败的结果。这种疾病在手术切除前很少能确诊。临床表现、影像学检查、手术发现和组织学表现都是正确诊断这种非常罕见的颈部囊性肿胀鉴别诊断的重要组成部分。
