# Exploring Diagnostic Complexities: A Case Report of Osteitis Condensans Ilii and Osteitis Pubis

## TL;DR

This case report describes a rare combination of two bone conditions in a young woman, highlighting their diagnostic challenges and lack of definitive treatment.

## Contribution

The novelty lies in presenting a rare co-occurrence of osteitis condensans ilii and osteitis pubis in a young female patient.

## Key findings

- MRI confirmed the presence of bilateral osteitis condensans ilii and osteitis pubis in a 21-year-old female.
- Sclerotic fibrosis appeared distinct on MRI, aiding in differentiation from other back pain pathologies.
- No definitive treatment exists, with lifestyle modifications being the only preventive measure.

## Abstract

Osteitis condensans ilii (OCI) is a benign etiology of lumbago, characterized by its self-limiting nature. Referred to as hyperostosis triangularis ilii, this condition is a rare occurrence, primarily manifesting in the female demographic. The etiology of this ailment remains undisclosed. Predominantly observed in the vicinity of the ileum, it may be erroneously interpreted as the involvement of the sacroiliac joint. Not characterized by inflammation, this disorder commonly emerges as a postpartum sequela in females. Osteitis pubis is a constrained inflammatory disorder characterized by pain affecting the pubic bones, joints, and associated tendons. This condition has been documented following instances of trauma, pelvic surgical procedures, childbirth, excessive athletic activity, and certain rheumatic ailments. We present a case of bilateral OCI with osteitis pubis in a 21-year-old female who presented with persistent lumbago as evidenced by radiological findings. Magnetic resonance imaging (MRI) corroborated the diagnostic procedures, indicating the presence of OCI with osteitis pubis. Sclerotic fibrosis exhibited a distinctly delineated and compact appearance on MRI, facilitating its differentiation from other pathologies linked to back pain. Regrettably, there exists no definitive remedy for these conditions, with lifestyle adjustments representing the sole measure that may aid in preventing disease recurrence.
