Summary
A patient with lower back and thigh pain, previously treated with corticosteroids, was diagnosed with a Staphylococcus aureus iliacus muscle abscess. Prompt surgical drainage and antibiotics led to recovery, highlighting the importance of imaging for diagnosis.
Area of Science:
- Infectious Diseases
- Musculoskeletal Disorders
- Medical Imaging
Background:
- A 55-year-old male presented with symptoms mimicking discogenic pain.
- Previous hospitalization for acute hepatitis involved high-dose parenteral hydrocortisone therapy.
Observation:
- The patient experienced severe right hip pain, inability to stand, and a positive psoas sign.
- Elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels were noted.
- Abdominal sonography and MRI revealed a right iliacus muscle abscess.
Findings:
- Abscess culture identified Staphylococcus aureus as the causative agent.
- Surgical debridement, drainage, and antibiotic treatment (cephazolin and gentamicin) were administered.
- Post-treatment, ESR and CRP levels normalized within three weeks.
Implications:
- This case underscores the importance of considering iliacus muscle abscess in patients with persistent hip and back pain, especially after corticosteroid use.
- Accurate diagnosis relies on a combination of thorough physical examination and advanced imaging modalities like MRI.
- Early recognition and appropriate management, including surgical intervention and antibiotics, are crucial for favorable outcomes.
