The kidney is an unconventional site for thyroid metastasis. As of the writing of this article, only about 30 cases have been reported. It presents like a renal mass. We are reporting a man with thyroid carcinoma presenting with distant metastasis to the kidney. He had complaints of abdominal pain and haematuria. Initial imaging suggested a left renal mass. A diagnosis of renal cell carcinoma was made and a nephrectomy was performed. Histopathology revealed it to be a metastasis from cancer of the thyroid gland. Subsequently, an ultrasound of the thyroid gland was performed, which showed a malignant appearing thyroid nodule. Correlative bone scan showed uptake at multiple skeletal sites. Total thyroidectomy was done and it was found to be papillary thyroid cancer. Subsequently, high dose radioactive iodine was administered. The patient was followed up and has recently found to have metastasis to the brain and is undergoing radiotherapy.
肾脏是甲状腺转移的一个非常规部位。截至本文撰写时，仅报告了约30例病例。它表现为肾脏肿块。我们报告了一名患有甲状腺癌并出现远处肾脏转移的男性。他有腹痛和血尿的症状。初步影像学检查提示左肾肿块。诊断为肾细胞癌并进行了肾切除术。组织病理学显示它是甲状腺癌的转移灶。随后，对甲状腺进行了超声检查，发现一个外观呈恶性的甲状腺结节。相关的骨扫描显示多个骨骼部位有摄取。进行了全甲状腺切除术，发现是乳头状甲状腺癌。随后，给予了高剂量放射性碘。对患者进行了随访，最近发现有脑转移，正在接受放疗。
