副甲狀腺癌及副甲狀腺機能亢進產生超級影像－病例報告

一位33歲女性患者在右頸部有摸到硬塊，超音波檢查發現在右頸部副甲腺處有低回音的腫塊(hypoechogenic mass)，血清檢驗發現這位患者甲狀腺促進激素(TSH)為15.19 ulU/ml（參考值為：0.35-4.94），核醫甲狀腺檢查，甲狀腺攝取值為0.27%（參考值為：0.4%-4.0%），報告指出在甲狀腺發現有2個功能性甲狀腺結節(functioning thyroid nodules)：核醫副甲狀腺檢查，在延遲相（2小時）發現在右側甲狀腺底部(thyroid bed)有明顯活性聚積；核醫骨骼檢查，發現有超級影像(super scan)現象，綜合上述核醫檢查，患者在右側副甲狀腺或兩側副甲狀腺可能為腺瘤或機能亢進；安排病理切片檢查，病理切片報告為副甲狀腺瘤(adenocarcinoma)。

Several recent studies have shown (superscript 99m)Tc-MIBI its ability in parathyroid adenoma, after IV injection, (superscript 99m)Tc-MIBI appear to localize very rapidly (less than 5 minutes) in both parathyroid adenomas and thyroid tissue, Its washout from parathyroid adenomas appears to be slow, unlike from normal thyroid tissue, which is characterized by a relatively fast washout over 2-3 hours .The 2-hour delayed (superscript 99m)Tc-MIBI imaging shows significantly residual tracer activity near the right lower thyroid bed, in addition, (superscript 99m)Tc-MDP bone scan reveals a metabolic super-scan pattern. Conclude the nuclear medicine physician hyperthyroidism should be considered first, diffuse bony metastates can not rule out. Histology shows the sections of 0.3cm of grayish tissue of parathyroid, it contains tumor cell only, no capsule, no normal parathyroid tissue, it is adenocarcinoma.
