甲状腺内甲状旁腺功能亢进：甲状旁腺手术失败的一个潜在原因。

J R Soc Med. 1981 Jan;74(1):49-52.

Four patients with hyperfunctioning intrathyroid parathyroid are reported. In each case the intrathyroid parathyroid was embedded within the thyroid parenchyma and appeared as a solitary 'cold' thyroid nodule by radioactive iodine scanning. It is believed that the intrathyroid parathyroid evolves as the lateral lobe of the thyroid fuses with the isthmus in the early development of the thyroid. Embryologically, and intrathyroid parathyroid is thus likely to be the superior gland. When the superior parathyroid gland is missing at the time of exploration, a nodule within the ipsilateral lobe of the thyroid may well be an intrathyroid parathyroid. Under these conditions, lobectomy for the exclusion of such a gland is mandatory.

报告了4例甲状腺内甲状旁腺功能亢进的患者。在每例病例中，甲状腺内甲状旁腺均包埋于甲状腺实质内，放射性碘扫描显示为单个“冷”甲状腺结节。据信，甲状腺内甲状旁腺是在甲状腺早期发育过程中，甲状腺侧叶与峡部融合时演变而来的。因此，从胚胎学角度来看，甲状腺内甲状旁腺很可能是上位腺体。当探查时上位甲状旁腺缺失时，甲状腺同侧叶内的结节很可能是甲状腺内甲状旁腺。在这些情况下，必须进行叶切除术以排除这样的腺体。
