Paraganglioma is a neuroendocrine tumor that originates from extraadrenal chromaffin cells. Primary thyroid paraganglioma is an extremely rare neoplasm. In this study, an exceptionally uncommon case of recurrent mediastinal malignant paraganglioma with primary origin from thyroid gland is presented. Median resternotomy, resection of left brachiocephalic vein, and extirpation of the mediastinal tumor were performed successfully. Commonly, it is preoperatively misdiagnosed and has unpredictable biological behavior. Incorrect diagnosis results in disastrous consequences for the patient, and consequently, correct pre- and postoperative diagnoses promise an optimal treatment plan and good prognosis. Long-term follow-up is indicated in all patients due to the risk of recurrence and distant metastases.
