Rarely, ectopic thyroid tissue can coexist with an eutopic thyroid. Technetium pertechnetate scan is peculiar for thyroid tissue uptake. However, DOTANOC uptake in mediastinal ectopic thyroid has been rarely reported. We present a unique case of an ectopic mediastinal thyroid mass that did not show any uptake on a pertechnetate scan and showed significantly increased uptake on Ga-DOTANOC positron emission tomography-computed tomography with an eutopic cervical thyroid with normal pertechnetate and physiological mild DOTANOC uptake.
异位甲状腺组织很少会与正常位置的甲状腺共存。高锝酸盐扫描对甲状腺组织摄取具有特异性。然而，关于纵隔异位甲状腺摄取DOTANOC的报道很少。我们报告了一例独特的纵隔异位甲状腺肿块病例，该肿块在高锝酸盐扫描中未显示任何摄取，而在Ga-DOTANOC正电子发射断层扫描-计算机断层扫描中显示摄取显著增加，同时正常位置的颈部甲状腺在高锝酸盐扫描中摄取正常且在生理状态下有轻度DOTANOC摄取。
