【摘要】 原发性甲状旁腺功能亢进症（PHPT）由甲状旁腺腺瘤（癌）或增生导致，大多数的甲状旁腺腺瘤可通过99mTc-MIBI甲状旁腺显像和甲状腺B超发现。本文报告1例由甲状旁腺腺瘤引起的老年PHPT患者，其腺瘤部分液化形成囊肿，同时合并甲状腺结节。其99mTc-MIBI甲状旁腺显像与甲状腺超声结果并不一致，给定位诊断带来了一定的困难。通过甲状旁腺肿物囊液穿刺液测定甲状旁腺素水平，确定了病变的位置，给予降钙及手术等治疗后，患者症状明显好转，预后较好。更多还原

【Abstract】 Primary hyperparathyroidism(PHPT)is caused by parathyroid adenoma(cancer)or hyperplasia. Most parathyroid adenomas can be found by 99mTc-MIBI parathyroid imaging and thyroid B-ultrasonography. This case is an elderly patient with primary hyperparathyroidism caused by parathyroid adenoma. The adenoma was partially liquefied to forma cyst with thyroid nodules. The results of 99mTc-MIBI parathyroid imaging and thyroid ultrasound are not consistent,which brings some difficulties to the localization diagnosis. Parathyroid hormone concentration was measured by puncture fluid of cystic fluid of parathyroid mass to conform the location of the primary lesion. After calcium reduction and operation,the patient’s symptoms improved significantly and the prognosis was good.更多还原
