Abstract

Possible thyroiditis was suspected in a 56-year-old man who initially presented sore throat because laboratory examinations revealed decreased serum thyroid hormone and the Tc-pertechnetate scintigraphy showed no tracer uptake by the thyroid gland. However, subsequent examination demonstrated that the absence of pertechnetate activity in the thyroid was due to complete replacement of thyroid gland by the metastasis from lung adenocarcinoma, which was unknown at the initial presentation.

摘要

怀疑该 56 岁男性患有甲状腺炎，因为实验室检查显示血清甲状腺激素降低，而 Tc-过锝酸盐闪烁显像显示甲状腺无示踪剂摄取。然而，后续检查表明，甲状腺内无过锝酸盐活性是由于肺癌转移完全取代了甲状腺，而这在初次就诊时并不知晓。
