# Iliopsoas Abscess Heralding the Diagnosis of Crohn's Disease in a Young Male

## TL;DR

A young man with Crohn's disease developed a rare iliopsoas abscess, which was successfully treated with drainage, antibiotics, and infliximab.

## Contribution

This case highlights the importance of early diagnosis and personalized treatment for Crohn's-related iliopsoas abscess.

## Key findings

- CT imaging and colonoscopy confirmed a fistulous connection between the abscess and terminal ileum.
- Treatment with PCD, antibiotics, and infliximab led to successful management of the abscess.
- Multidisciplinary care is essential to prevent complications and recurrence in such cases.

## Abstract

Iliopsoas abscess (IPA) is a rare but potentially life-threatening complication that may occur in patients with Crohn's disease. We present the case of a 28-year-old male with Crohn's disease who developed a complicated IPA. Diagnosis was confirmed via CT imaging and colonoscopy, revealing a fistulous connection to the terminal ileum. The treatment involved percutaneous drainage (PCD), antibiotics, and infliximab. Timely diagnosis, appropriate imaging, and multidisciplinary care are critical to prevent morbidity and recurrence in patients with Crohn's disease complicated by IPA. This case highlights the importance of personalized treatment strategies and close follow-up in managing Crohn's-related IPA.
