## TL;DR

A 36-year-old healthy man developed a rare psoas abscess with no known risk factors, suggesting other unknown causes may exist.

## Contribution

Reports a rare case of psoas abscess in a healthy individual with no known risk factors.

## Key findings

- Psoas abscess occurred in a 36-year-old male without underlying health conditions.
- The case suggests the possibility of unknown contributors to psoas abscess formation.
- Emphasizes the need for broad diagnostic consideration even in the absence of typical risk factors.

## Abstract

Psoas abscess is an uncommon and often difficult condition to diagnose due to its vague and variable symptoms. While certain signs such as fever, back pain, and difficulty walking may be associated with it, they are not consistently present in all cases. These abscesses can arise spontaneously or as a result of an underlying condition. Spontaneous cases are more frequently observed in individuals with compromised immune systems or other chronic health issues, although they may occasionally occur without any clear predisposing factors. We describe a case involving a 36-year-old male without known underlying conditions who developed a spontaneous psoas abscess. This case highlights the importance of maintaining a broad diagnostic perspective, even when conventional risk factors are absent, and raises the possibility that other, less well-defined contributors to this condition may exist.
