Solitary metastasis of occult thyroid carcinoma to the anterior mediastinum is very rare. A 65-year-old woman was examined for anterior mediastinal tumor based on the FDG accumulation on PET. We resected the tumor by video-assisted thoracic surgery. A pathological examination revealed that the tumor was lymph node metastasis of papillary thyroid carcinoma. The postoperative examination showed that the tumor was a solitary lymph node metastasis of occult thyroid carcinoma. Primary thyroid carcinoma has not appeared in 2 years since the surgery, and careful follow-up has been continued.
隐匿性甲状腺癌孤立性转移至前纵隔极为罕见。一名65岁女性因PET上的FDG摄取而接受前纵隔肿瘤检查。我们通过电视辅助胸腔镜手术切除了肿瘤。病理检查显示该肿瘤为甲状腺乳头状癌的淋巴结转移。术后检查表明该肿瘤是隐匿性甲状腺癌的孤立性淋巴结转移。自手术以来2年未出现原发性甲状腺癌，目前仍在继续进行密切随访。
