原发性甲状旁腺功能亢进的定位诊断

Localizing diagnosis of primary hyperparathyroidism

目的 探讨超声、ECT、CT和MRI对原发性甲状旁腺功能亢进(primaryhyperparathy roidism ,PHPT)的定位诊断价值。方法 回顾性分析1990年1月1日至2 0 0 4年3月31日34例手术治疗的PHPT患者的临床资料。结果 2 5例患者手术前行超声检查,其中2 2例手术前的超声定位与术中所见相符合,诊断的符合率为88%。2 1例患者手术前行ECT检查,其中2 0例患者与手术中所见相符合,诊断符合率为95 %。19例患者手术前行CT检查,13人与手术中定位相一致,诊断符合率6 9 %。3例患者手术前行MRI检查均发现病变并且与手术中所见相一致。结论 超声和99mTc MIBI应该作为首选的定位检查方法,尤其是二者联合应用可以提高定位诊断的准确率。

Objective To evaluate the diagnostic value of US, ECT, CT and MRI in primary hyperparathyroidism (PHPT). Methods Data of 34 PHPT patients with diagnosis confirmed by postoperative pathology were retrospectively reviewed from January 1, 1990, through March 31, 2004. Results The preoperative diagnosis in 22 out of 25 cases (88%) undergoing preoperative ultrasonography of the neck with a positive result was verified by intraoperative findings. For 99m Tc-MIBI, CT and MRI, the positive results were 95%, 69% and 100% respectively. Conclusion Ultrasonography and 99m Tc-MIBI should be considered as the first choice for preoperative loci localization in patients with PHPT. Ultrasonography and 99m Tc-MIBI in combination is more sensitive and accurate for the localization of PHPT.
