Primary hyperparathyroidism is due to an adenoma in 85% of cases. In 10% of cases, the parathyroid adenoma may be in an ectopic location. Ten per cent of these ectopic adenomas are located in the mediastinum. Imaging modalities performed in persistent or recurrent hyperparathyroidism include ultrasound, MIBI scintigraphy, venous blood sampling, helical CT and MRI. The authors report 3 cases of ectopic adenoma located in the mediastinum, where pre-operative diagnosis was confirmed using cardiac MRI sequences.
原发性甲状旁腺功能亢进症在85%的病例中是由腺瘤引起的。在10%的病例中，甲状旁腺腺瘤可能位于异位位置。这些异位腺瘤中有10%位于纵隔。对持续性或复发性甲状旁腺功能亢进症进行的影像学检查包括超声、甲氧基异丁基异腈闪烁扫描、静脉血采样、螺旋CT和MRI。作者报告了3例位于纵隔的异位腺瘤病例，术前诊断通过心脏MRI序列得以证实。
