An infant girl was referred for thyroid screening. The T4 value was 5.0 micrograms/dl (normal 5.0-13.0 micrograms/dl), and the thyroid-stimulating hormone-radioimmunoassay value was greater than 60.0 microIU/ml (normal 0-10.0 microIU/ml). Imaging failed to demonstrate thyroid tissue in the normal anatomic position in the neck. A focal collection of activity was seen, however, on a scan corresponding to the position of the base of the tongue. The finding is consistent with the diagnosis of a lingual (undescended) thyroid.
一名女婴因甲状腺筛查前来就诊。其甲状腺素（T4）值为5.0微克/分升（正常范围5.0 - 13.0微克/分升），促甲状腺激素放射免疫测定值大于60.0微国际单位/毫升（正常范围0 - 10.0微国际单位/毫升）。影像学检查未在颈部正常解剖位置发现甲状腺组织。然而，在对应于舌根位置的扫描中发现了一个局灶性放射性聚集区。这一发现符合舌部（未降）甲状腺的诊断。
