The majority of middle mediastinal cysts are benign diseases. However, some cases of middle mediastinal cysts are revealed to be malignant tumor. We herein report a case of a middle mediastinal cyst, which proved to be a right paratracheal lymph node metastasis from the thyroid papillary carcinoma. The patient was a 67-year-old lady who had underwent thyroidectomy and regional lymph node dissection for papillary thyroid carcinoma 6 years before. Follow-up computed tomography revealed a growing cyst at the right-side of the intrathoracic trachea. Metastasis from thyroid cancer was suspected from her history. The right upper mediastinal lymphadenectomy through thoracoscopy was performed. Pathologically, the cyst was diagnosed as a metastasis from thyroid cancer, showing cystic change.
大多数中纵隔囊肿是良性疾病。然而，一些中纵隔囊肿病例被发现是恶性肿瘤。我们在此报告一例中纵隔囊肿，结果证明是甲状腺乳头状癌的右气管旁淋巴结转移。患者为一名67岁女性，6年前因甲状腺乳头状癌接受了甲状腺切除术和区域淋巴结清扫术。随访计算机断层扫描显示胸段气管右侧有一个不断增大的囊肿。根据她的病史怀疑是甲状腺癌转移。通过胸腔镜进行了右上纵隔淋巴结切除术。病理检查显示，该囊肿被诊断为甲状腺癌转移，呈现囊性改变。
