Case ReportA 58-year-old male patient presented to our department for surgical management of a right neck nodule and low fever over the past 2 weeks. Preoperative evaluation, which included chest CT scan, MRI and scintigraphy （^99mTc）, revealed round and clear boundary intrathoracic ectopic thyroid tissue at the right side of the anterior mediastinum and an enlarged lymph node in the right neck. The preoperative general image diagnosis concluded a malignant ectopic intrathoracic goiter （Figs. 1-3）. The lymph node biopsy confirmed a metastatic papillary adenocarcinoma of the thyroid.. The tumor was resected via a cervical collar incision （Fig.4）. Bilateral hemithyroidectomy and cervical lymph node dissection were also performed. We noticed that the intrathoracic thyroid was not connected to the cervical thyroid. Blood was supplied from the intrathoracic vessels, thereby establishing the diagnosis of an ectopic intrathoracic thyroid. Final pathologic diagnosis was a papillary adenocarcinoma of the thyroid in an ectopic intrathoarcic goiter with involved lymph node. The postoperative course was uneventful.
