METHODS: This case report presents a patient with primary hyperparathyroidism and a parathyroid adenoma detected solely through 68Ga-PSMA-11 PET/CT, typically used for prostate cancer diagnosis. The lesion observed in the PET/CT was confirmed as a parathyroid adenoma through laboratory evaluation, while other imaging techniques failed to detect it.
CONCLUSIONS: This finding suggests that the PSMA ligands\' particular affinity for neovascularisation in focal changes may facilitate the visualisation of parathyroid adenomas. The utilisation of 68Ga-PSMA-11 PET/CT in primary hyperparathyroidism could potentially improve the preoperative localization of parathyroid adenomas when conventional imaging methods are inconclusive.
方法:本病例报告显示1例仅通过68Ga-PSMA-11PET/CT检测的原发性甲状旁腺功能亢进症和甲状旁腺腺瘤,通常用于前列腺癌的诊断。通过实验室评估,PET/CT中观察到的病变被证实为甲状旁腺腺瘤。而其他成像技术未能检测到它。
结论:这一发现表明,PSMA配体对局灶性变化中新生血管形成的特殊亲和力可能有助于甲状旁腺腺瘤的可视化。当常规成像方法不确定时,在原发性甲状旁腺功能亢进症中使用68Ga-PSMA-11PET/CT可能会改善甲状旁腺腺瘤的术前定位。
