Incidentally discovered intrathoracic extra-adrenal pheochromocytoma during preoperative screening

Abstract

Introduction: We are reporting a case of an incidental mass later diagnosed as an extradural pheochromocytoma at t2-t4 level during a presurgical work up for a gynecological procedure. Only a few cases of extradural paravertebral tumors are described in literature. case report: this is a clinical case of an asymptomatic 26-year-old female with an incidental finding of thoracic mass in chest X-ray during preoperative screening for myomectomy. Work up for this mass showed elevated plasma and urinary metanephrine levels which was consistent to pheochromocytoma. computed tomography, magnetic resonance imaging and metaiodobenzylguanidine scans demonstrate a mass originating from thoracic spine with cord compression, no adrenal mass, multifocal disease or metastasis. Prior to surgery, the patient was treated with phenoxybenzamine and metoprolol to decrease hemodynamic instability during surgical procedure and also embolization to the arteries supplying the mass to decrease intraoperative bleeding.
