# Large Nonfunctioning Anterior Mediastinal Epiaortic Paraganglioma

## TL;DR

This paper reports a rare case of a patient with two different paragangliomas, requiring aortic replacement and highlighting the need for thorough screening.

## Contribution

The novelty lies in the rare coexistence of a carotid body tumor and a large nonfunctioning epiaortic paraganglioma requiring aortic surgery.

## Key findings

- A patient had a carotid body tumor and a large nonfunctioning epiaortic paraganglioma.
- The case required ascending aorta replacement due to the tumor's location.
- Extrathoracic neuroendocrine tumors should prompt screening for multiple tumors.

## Abstract

We present a very rare case of a carotid body tumor accompanied by a large nonfunctioning epiaortic paraganglioma requiring ascending aorta replacement. Even though multiple paragangliomas in different locations in a single patient are highly uncommon, preoperative discovery of an extrathoracic neuroendocrine tumor should prompt full screening for the presence of multiple tumors.
