摘要

異位性副甲狀腺是造成副甲狀腺機能亢進術後復發的主要原因，未沉降副甲狀腺是一個罕見但潛在造成手術失敗的原因，卻很容易被忽略。Tc-99m sestamibi副甲狀腺造影輔以單光子斷層／電腦斷層影像能夠更精準的找出潛藏的病灶。我們報告兩位末期腎病變長期接受透析治療合併次發性副甲狀腺機能亢進之患者，副甲狀腺切除術後追蹤發現持續性與復發性副甲狀腺機能亢進，Tc-99m sestamibi副甲狀腺造影輔以單光子斷層／電腦斷層影像正確定位出未沉降副甲狀腺，經手術切除後證實確是副甲狀腺增生組織。

Ectopic parathyroid gland is the major cause of persistent or recurrent hyperparathyroidism after parathyroidectomy. Undescended parathyroid gland, though very rare, is a potential cause of surgical failure. Tc-99m sestamibi parathyroid scintigraphy with single photon emission computed tomography/computed tomography (SPECT/CT) is helpful to identify the undescended parathyroid gland. We reported two patients with end stage renal disease and secondary hyperparathyroidism. Persistent and recurrent hyperparathyroidism were noted after parathyroidectomy. Tc-99m sestamibi parathyroid scintigraphy with SPECT/CT images accurately identified undescended parathyroid glands. They received surgical removal of the lesions and the pathological results were parathyroid hyperplasia.
