Two thyroidectomized patients with a history of differentiated thyroid carcinoma are presented who had nonmetastatic mediastinal 131I uptake following therapeutic doses of 131I. Chest CT scans in both patients demonstrated an anterior mediastinal mass. Surgical excision in one patient and a percutaneous CT-guided fine needle aspiration biopsy in the other disclosed normal thymus tissue. Iodine-131 uptake in the anterior mediastinum in patients thyroidectomized for follicular or papillary thyroid carcinoma may represent the thymus.
本文报告了两名有分化型甲状腺癌病史的甲状腺切除患者，他们在接受治疗剂量的131I后出现纵隔非转移性131I摄取。两名患者的胸部CT扫描均显示前纵隔肿块。其中一名患者接受了手术切除，另一名患者接受了经皮CT引导下细针穿刺活检，结果均显示为正常胸腺组织。因滤泡状或乳头状甲状腺癌行甲状腺切除的患者前纵隔出现碘-131摄取可能代表胸腺。
