We present a case of ectopic intrathoracic multinodular goiter and correlate the magnetic resonance imaging appearance with the histological findings.
A 72-year-old man was referred to our institute with a two month history of cough. The chest radiograph showed a mass located in the mediastinum. A chest computed tomography scan, showed an enhancing mass at the right side of the middle mediastinum where magnetic resonance images, demonstrated a multicystic mass. The mass was excised through a right lateral thoracotomy and histologically it proved to be an ectopic multinodular goiter.
Although ectopic intrathoracic multinodular goiter is a rare entity, it should be considered in the differential diagnosis of mediastinal masses. The preoperative diagnosis is important as, unlike substernal goiter which is surgically approached through the neck, the ectopic thyroid is treated by thoracotomy.
我们报告一例异位胸内多结节性甲状腺肿病例，并将磁共振成像表现与组织学结果进行关联。
一名72岁男性因咳嗽两个月被转诊至我院。胸部X线片显示纵隔有一肿块。胸部计算机断层扫描显示中纵隔右侧有一强化肿块，磁共振成像显示为多囊性肿块。通过右侧开胸手术切除该肿块，组织学检查证实为异位多结节性甲状腺肿。
尽管异位胸内多结节性甲状腺肿是一种罕见疾病，但在纵隔肿块的鉴别诊断中应予以考虑。术前诊断很重要，因为与通过颈部手术治疗的胸骨后甲状腺肿不同，异位甲状腺需通过开胸手术治疗。
