# Lemierre's syndrome: Pediatric clinical case presentation

## TL;DR

This paper presents a pediatric case of Lemierre's syndrome and emphasizes the role of imaging in diagnosing and monitoring the condition.

## Contribution

The paper contributes a detailed pediatric clinical case highlighting the use of CT and MRI in diagnosing Lemierre's syndrome.

## Key findings

- Computed tomography and MRI are effective in identifying retropharyngeal abscesses and jugular thrombosis in Lemierre's syndrome.
- A 2-month-old child presented with LS complicated by mediastinitis and cervical empyema.
- Early diagnostic imaging is crucial for managing and following up on Lemierre's syndrome cases.

## Abstract

Lemierre Syndrome (LS) is a rare infectious condition characterized by septic thrombosis of the internal jugular vein and septic embolization, mainly caused by Fusobacterium necrophorum. Diagnostic Imaging plays a key role in the early diagnosis and follow-up of the syndrome. This article reviews the available literature on radiology applied in LS and analyzes a pediatric clinical case that highlights the importance of computed tomography (CT) and magnetic resonance imaging (MRI) for identifying retropharyngeal abscesses and jugular thrombosis. The case involves a 2-month-old child diagnosed with LS complicated by mediastinitis, cervical empyema, and septic thrombosis of the internal jugular vein as complication.
