Nodular goiter is a common disease in Taiwan, and substernal or intrathoracic goiters are not infrequent. However, intrathoracic goiters are mainly of the secondary type and primary intrathoracic goiters are rarely seen. We report a 55-year-old woman who was incidentally found to have an ectopic goiter located in the anterior upper mediastinum with the initial presenting symptom of productive cough. Imaging studies including chest X-ray and computed tomography identified the lesion, and 131I-uptake scan showed weak uptake in the thorax. Surgical removal via thoracotomy was performed and the diagnosis was confirmed by pathology. A primary intrathoracic goiter, although rare, should also be considered in the differential diagnosis of mediastinal tumor.
结节性甲状腺肿在台湾是一种常见疾病，胸骨后或胸内甲状腺肿也并不罕见。然而，胸内甲状腺肿主要是继发性的，原发性胸内甲状腺肿很少见。我们报告一位55岁女性，她偶然发现前上纵隔有一个异位甲状腺肿，最初的表现症状是咳痰。包括胸部X光和计算机断层扫描在内的影像学检查确定了病变，131I摄取扫描显示胸部摄取较弱。通过开胸手术进行了切除，病理检查确诊。原发性胸内甲状腺肿虽然罕见，但在纵隔肿瘤的鉴别诊断中也应予以考虑。
