Intrathyroid metastases are uncommon. Clinically, the distinction may be difficult with thyroid malignant tumor.
A 76-year-old woman was referred to our department for an evaluation of a dysphonia. She had a past history of renal cancer 6 months ago. A multinodular goiter was noticed at the palpation. Left recurrent laryngeal nerve palsy was observed; there was no cervical lymph node. Fine-needle aspiration was not contributive. Computed tomography confirmed the multinodular goiter. Total thyroidectomy was performed and final histologic examination revealed a metastasis of a renal cancer.
Even if intrathyroid metastasis are rare, the practitioner must suggest the diagnosis if the patient had a thyroid tumor and a past history of cancer. A fine-needle aspiration can help the diagnosis. The surgical management is recommended for isolated metastasis to the thyroid gland especially in renal cancer.
甲状腺内转移并不常见。临床上，与甲状腺恶性肿瘤鉴别可能困难。
一名76岁女性因声音嘶哑前来我科评估。她6个月前有肾癌病史。触诊时发现有结节性甲状腺肿。观察到左侧喉返神经麻痹；无颈部淋巴结。细针穿刺未提供有效信息。计算机断层扫描证实为结节性甲状腺肿。行甲状腺全切除术，最终组织学检查显示为肾癌转移。
即使甲状腺内转移罕见，但如果患者有甲状腺肿瘤且有癌症病史，医生必须考虑该诊断。细针穿刺有助于诊断。对于孤立性甲状腺转移，尤其是肾癌转移，建议手术治疗。
