Surgical treatment option for incidental azygos vein aneurysm: a case report

Azygos vein aneurysms (AVA) are rare pathologies of the thorax that can mimic a posterior mediastinal mass. Patients with AVA may be asymptomatic, or present with chest pain, pulmonary embolisms, and acute rupture. Currently, there are no standardized guidelines for treatment. Management varies from interval surveillance, prophylactic oral anticoagulation or anti-platelet, endovascular embolization, and/or surgical resection. We present the case of a 45-year-old female who was found to have an incidental azygos vein aneurysm. She was asymptomatic and underwent robotic assisted mediastinal mass resection with no intra-operative or post-operative complications.
