At presentation, the patient\u2019s blood pressure was 190\/120\u00a0mmHg. Chest computed tomography and magnetic resonance imaging revealed a left paravertebral mass in the posterior mediastinum. <jats:sup>123<\/jats:sup>I-metaiodobenzylguanidine scanning revealed focally high tracer uptake in the left paravertebral area. The metanephrine level in the urine was elevated, confirming a rare, catecholamine-producing, functional paraganglioma in the posterior mediastinum. Before surgery, the patient was prepared by orally administering \u03b1- and \u03b2-adrenergic blockers. The mass was then resected via a lateral thoracotomy.
