Management of an anterior mediastinal pheochromocytoma causing tracheomalacia.
Thoracic paragangliomas are rare tumors that arise from extra-adrenal chromaffin cells and have the capacity to secrete catecholamines. Surgical excision is the optimal treatment of these tumors as they are resistant to chemotherapy and radiation therapy. Although these tumors are most commonly found in the abdomen, 10% of paraganagliomas are located in the thorax, usually in the posterior mediastinum. Occasionally these tumors present in the anterior mediastinum, which can pose a significant surgical challenge due to the proximity of the great vessels and airway. In this report we describe the treatment of an anterior mediastinal pheochromocytoma that presented with tracheal obstruction and required pulmonary artery reconstruction and airway stenting.
