# Noninfectious Necrotizing Aortitis With Predominantly Neutrophilic Infiltrate

## TL;DR

This paper reports a rare case of noninfectious aortitis in a young man, showing that a neutrophilic infiltrate can occur without infection.

## Contribution

The novelty lies in demonstrating that noninfectious aortitis can present with a neutrophilic infiltrate, challenging assumptions about its causes.

## Key findings

- A case of noninfectious ascending aortitis was identified in a young, previously healthy man.
- Histopathological analysis revealed a predominantly neutrophilic infiltrate without evidence of infection.

## Abstract

Aortitis can be either infectious or noninfectious, and cases of noninfectious aortitis are not well understood. Our study presents a case of noninfectious ascending aortitis in a relatively young, previously healthy man, characterized by a predominantly neutrophilic infiltrate on histopathological examination without an inciting microorganism. This case report highlights that a neutrophilic infiltrate does not necessarily indicate an infectious etiology in ascending aortic aneurysms.
