Abstract：
Hyperfunctioning parathyroid glands may be rarely located in the thyroidal parenchyma and not identified by imaging or during surgical procedures. We present three patients with primary hyperparathyroidism related to hyperfunctioning intrathyroidal parathyroid retrospectively selected among 732 cases from own Institutional parathyroid PET/CT registry from 2018 to 2022. Intrathyroidal parathyroids showed intense 18F-fluorocholine uptake but a variable echographic pattern, inconstant 99mTc-MIBI uptake, and atypic iodine-contrast enhancement. Although rare, the possibility of an intrathyroidal parathyroid should be considered when no hyperfunctioning gland is found on preoperative imaging and thorough bilateral neck exploration.
摘要：
功能亢进的甲状旁腺可能很少位于甲状腺实质中，并且无法通过成像或在外科手术中识别。我们介绍了2018年至2022年从自己的机构甲状旁腺PET/CT注册表中的732例患者中回顾性选择的3例原发性甲状旁腺功能亢进与甲状腺内甲状旁腺功能亢进相关的患者。甲状腺内甲状旁腺表现出强烈的18F-氟胆碱摄取，但回声图可变，不恒定的99mTc-MIBI摄取，和非典型碘对比增强。虽然罕见，如果在术前成像和彻底的双侧颈部探查中没有发现功能亢进的腺体，则应考虑甲状腺内甲状旁腺的可能性。
