Lingual thyroid is an uncommon cause of oropharyngeal mass, due to a congenital anomaly of thyroidal development and migration: It is defined precisely as the presence of thyroid tissue in the midline of the tongue base between circumvallatae papillae and the epiglottis. We report a case of lingual thyroid in which the integration of clinical data, sonography, color-duplex Doppler, MRI and scintigraphy was determinant in demonstrating the disease. A 22-year-old woman presented with a sensation of foreign body in the throat, dysphonia, dyspnoea and dysphagia; we performed sonography (7.5 MHz linear probe), color Doppler (7 MHz Doppler frequency, PRF 3500 Hz) and MRI (1.5 T, spin-echo T1- and T2-weighted images with administration of Gd-DTPA); a scan with 123I demonstrated a relevant uptake at the base of the tongue, but no uptake at the typical thyroid location. The gland was removed and partially transplanted in the strap muscles of the neck.
舌甲状腺是口咽肿物的一种罕见病因，源于甲状腺发育和迁移的先天性异常：确切地说，它被定义为舌根部中线处、轮廓乳头与会厌之间存在甲状腺组织。我们报告一例舌甲状腺病例，其中临床数据、超声检查、彩色双功多普勒、磁共振成像（MRI）和闪烁扫描的综合运用对确诊该病起到了决定性作用。一名22岁女性出现咽喉部异物感、声音嘶哑、呼吸困难和吞咽困难；我们进行了超声检查（7.5兆赫线性探头）、彩色多普勒检查（7兆赫多普勒频率，脉冲重复频率3500赫兹）和MRI检查（1.5特斯拉，静脉注射钆喷酸葡胺后的自旋回波T1加权和T2加权图像）；123碘扫描显示舌根部有明显摄取，但典型甲状腺部位无摄取。该腺体被切除并部分移植至颈部带状肌。
