We report a case of lingual thyroid. A woman presented with a few years history of mild dysphagia, cough and uncomfortable breathing when going to sleep at night. Laryngostroboscopy showed a mass lesion at the base of the tongue. A CT scan and thyroid scanning revealed a bilobar mass of thyroid tissue, compatible with a lingual thyroid. No thyroid gland was found at its usual location. The woman was euthyroid and since her symptoms were mild she was treated with thyroxin and observation. Lingual thyroid is a rare phenomenon caused by abnormal migration of thyroid cells during the first weeks of fetal life. Females are affected more often than males and although this condition is often asymptomatic, symptoms can occur, most often during puberty, pregnancy and menopause. On examination a mass is noted at the base of the tongue and the diagnosis is then confirmed with CT/MRI and thyroid scanning. Treatment can vary from observation to thyroxin medication, radioactive iodine and complicated surgical intervention, depending on the symptoms and the overall health of the patient.
我们报告一例舌甲状腺病例。一名女性有几年的轻度吞咽困难、咳嗽病史，且夜间入睡时呼吸不适。喉动态镜检查显示舌根部有一肿块病变。CT扫描和甲状腺扫描显示甲状腺组织呈双侧叶肿块，符合舌甲状腺表现。在其正常位置未发现甲状腺。该女性甲状腺功能正常，由于症状较轻，她接受了甲状腺素治疗并进行观察。舌甲状腺是一种罕见现象，由胎儿生命最初几周甲状腺细胞异常迁移引起。女性比男性更易受影响，尽管这种情况通常无症状，但也可能出现症状，最常见于青春期、孕期和更年期。检查时可在舌根部发现肿块，然后通过CT/MRI和甲状腺扫描确诊。治疗方法因症状和患者整体健康状况而异，从观察到甲状腺素药物治疗、放射性碘治疗以及复杂的手术干预不等。
