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

## TL;DR

This case report describes a rare azygos vein aneurysm in a 45-year-old woman treated successfully with robotic surgery.

## Contribution

The paper presents a novel surgical approach for managing an incidental azygos vein aneurysm.

## Key findings

- The patient was asymptomatic and had no complications during or after robotic-assisted surgery.
- Robotic surgery is a viable treatment option for azygos vein aneurysms.
- There are no standardized guidelines for treating this rare condition.

## Abstract

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.
