# Pyogenic Myositis: A Fulminant Presentation in an Immunocompromised Patient

## TL;DR

This paper presents a rare case of severe muscle infection in an immunocompromised patient that led to septic shock.

## Contribution

The case highlights the rare disseminated presentation of pyomyositis and its management in immunocompromised individuals.

## Key findings

- Severe pyogenic myositis can present as septic shock with disseminated muscle involvement.
- Prompt radiological diagnosis and multidisciplinary treatment are crucial for functional recovery.
- Pyomyositis should be considered in immunocompromised patients with muscle complaints and infection signs.

## Abstract

Pyomyositis, a purulent infection of an individual muscle group, is an infrequent condition, mostly occurring in immunocompromised patients. It is often caused by Staphylococcus aureus and most of the time restricted to a single muscle group, with disseminated presentations being exceptionally rare. We present a case of severe pyogenic myositis with disseminated muscle involvement, presenting as a septic shock in an immunocompromised patient. The case highlights the importance of considering pyomyositis in the differential diagnosis of a patient with hematogenous dissemination of a pyogenic agent and sustained muscle complaints. A prompt radiological diagnosis and a multidisciplinary approach to treatment are often necessary for a good functional outcome.
