Summary
Systemic lupus erythematosus (SLE) patients are at increased risk for developing iliopsoas muscle abscesses (IPA). Prompt diagnosis and treatment, including antibiotics and surgical drainage, are crucial for managing this uncommon condition.
Area of Science:
- Rheumatology
- Infectious Diseases
- Radiology
Background:
- Iliopsoas muscle abscess (IPA) is a rare condition, often linked to immunosuppression.
- Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by widespread inflammation and immunosuppression, both from the disease itself and its treatments.
Observation:
- This report details three cases of IPA in patients with SLE.
- Patients presented with fever and SLE-related symptoms, with partial improvement under SLE therapy.
- Pain suggestive of IPA was noted, and computed tomography (CT) confirmed the abscess in all cases.
Findings:
- In one patient, Staphylococcus aureus was isolated (primary IPA).
- Mycobacterium tuberculosis was identified in the other two patients.
- All patients required specific antimicrobial therapy and surgical drainage for successful treatment.
Implications:
- Systemic lupus erythematosus (SLE) should be considered a potential risk factor for developing iliopsoas muscle abscesses (IPA).
- The immunosuppressive state associated with SLE and its treatment contributes to this increased risk.
- Early recognition and combined medical-surgical management are essential for patients with SLE and suspected IPA.
