Parathyroid adenomas may have ectopic localizations, for example, intrathyroidal, which diagnosis is difficult. The present report illustrates this fact. A patient, 45 years old, euthyroidal, with a cold thyroidal nodule, underwent a right thyroidal lobectomy. Immediately after the operation, a tetany crisis occured with a Chovstek's sign and a 65 mg/l blood calcium level. The possibility of an accidental parathyroidectomy was evoked, and a second histological exam of the tumor showed the presence of a trabecular parathyroidal adenoma in the back of a vesicular thyroidal adenoma. The presence of this parathyroidal adenoma should have been suspected because of the occurence of nephretics colics in the antecedents, but there was a high blood uric acid level and the diagnosis of uric concretion was retained; no dosage of blood calcium level has been done.
甲状旁腺腺瘤可能有异位定位，例如甲状腺内，其诊断困难。本报告说明了这一事实。一名45岁的甲状腺功能正常患者，有一个甲状腺冷结节，接受了右侧甲状腺叶切除术。术后立即发生手足搐搦危象，伴有陶瑟征，血钙水平为65mg/l。引发了意外甲状旁腺切除的可能性，对肿瘤进行的第二次组织学检查显示，在泡状甲状腺腺瘤后方存在小梁状甲状旁腺腺瘤。由于既往有肾绞痛发作，本应怀疑存在这种甲状旁腺腺瘤，但当时血尿酸水平较高，故诊断为尿酸结石；未进行血钙水平测定。
