A 64-year-old woman was biochemically diagnosed with hyperparathyroidism. Technetium-99m sestamibi parathyroid scan demonstrated persistent uptake in the left lower pole of the thyroid. She underwent F-18 FDG PET due to unrelated causes. Incidentally, we found focal FDG accumulation in the lower portion of left thyroid lobe. An ultrasound showed a 2.2-cm nodule containing cystic component in the left lower pole of the thyroid. The intact PTH level in the cystic fluid was much higher than the serum intact PTH level, suggesting an intrathyroidal parathyroid adenoma. Left lobectomy revealed an intrathyroidal parathyroid adenoma in the left thyroid lobe.
一名64岁女性经生化检查诊断为甲状旁腺功能亢进。锝-99m甲氧基异丁基异腈甲状旁腺扫描显示甲状腺左下极持续摄取。因其他无关原因,她接受了F-18氟代脱氧葡萄糖正电子发射断层扫描(F-18 FDG PET)。偶然发现左甲状腺叶下部有局灶性FDG积聚。超声显示甲状腺左下极有一个2.2厘米的结节,含有囊性成分。囊液中完整甲状旁腺激素(PTH)水平远高于血清完整PTH水平,提示甲状腺内甲状旁腺腺瘤。左叶切除术显示左甲状腺叶内有一个甲状旁腺腺瘤。
