Abstract
Tl-201 and Tc-99m subtraction imaging is a well-established technique for detecting parathyroid adenomas. We report a case of a brown tumor of the upper sternum mimicking an ectopic mediastinal parathyroid adenoma on Tl-201 and Tc-99m subtraction imaging in a patient with hyperparathyroidism. This brown tumor showed Tl-201 uptake but not Tc-99m uptake and thus did not subtract out in this scan.
摘要
铊-201和锝-99m减影成像是检测甲状旁腺腺瘤的一项成熟技术。我们报告了1例胸骨上段棕色瘤病例，在1例甲状旁腺功能亢进患者的铊-201和锝-99m减影成像中，该棕色瘤酷似异位纵隔甲状旁腺腺瘤。此棕色瘤摄取铊-201但不摄取锝-99m，因此在该扫描中未能被减除。
