Two cases of papillary carcinoma of the thyroid are presented in which whole-body scans following therapeutic doses of iodine-131 revealed intense anterior mediastinal uptake. In both cases, the mediastinal uptake was absent from scans obtained after removal of the entire thymus. Histologically, the resected thymus glands showed hyperplasia and contained neither thyroid tissue nor metastatic foci of thyroid carcinoma. We therefore concluded that anterior mediastinal uptake of radioiodine may be caused by hyperplasia of the thymus.
本文报告了两例甲状腺乳头状癌病例，在给予治疗剂量的碘-131后进行的全身扫描显示前纵隔有强烈摄取。在这两例病例中，切除整个胸腺后获得的扫描显示纵隔摄取消失。组织学检查显示，切除的胸腺呈增生状态，既没有甲状腺组织也没有甲状腺癌转移灶。因此，我们得出结论，前纵隔放射性碘摄取可能是由胸腺增生引起的。
