# Conservative Treatment of an Unusual Presentation of Iliopsoas Phlegmon Related to Infected Intrauterine Contraceptive Device

## TL;DR

A 51-year-old woman with an infected intrauterine contraceptive device developed an unusual iliopsoas abscess, showing the importance of considering rare infection sources.

## Contribution

Highlights an unusual case linking an infected IUD to iliopsoas abscess, emphasizing the need for broader diagnostic consideration.

## Key findings

- Iliopsoas abscess was diagnosed in a patient with a nonspecific presentation.
- The infection was traced back to an infected intrauterine contraceptive device.
- Conservative treatment was effective in managing the condition.

## Abstract

Iliopsoas phlegmon/abscess is uncommon, and individuals often present with nonspecific symptoms. Diagnosis is often delayed and almost always requires advanced imaging techniques such as computed tomography or magnetic resonance imaging. We report a case of a 51-year-old woman who presented with right lower limb swelling and associated rash with imaging demonstrating iliopsoas abscess secondary to an infected intrauterine contraceptive device. This rare case highlights the nonspecific presentation of iliopsoas abscess and the need to consider unusual sources of infection such as an intrauterine contraceptive device in women presenting with iliopsoas phlegmon and abscess.
