Summary

Psoas abscesses, often secondary to gastrointestinal or osteoarticular issues, require drainage and prolonged antimicrobial therapy for effective treatment. Tuberculous psoas abscesses present insidiously, typically originating from spondylitis.

Area of Science:

  • Infectious Diseases
  • Musculoskeletal Infections
  • Radiology

Context:

  • Psoas abscesses are uncommon but serious infections.
  • Understanding their diverse etiologies and clinical presentations is crucial for timely diagnosis and treatment.
  • This study analyzes psoas abscess characteristics, differentiating between pyogenic and tuberculous forms.

Purpose:

  • To analyze the characteristics of psoas muscle abscesses.
  • To assess differences between pyogenic and tuberculous psoas abscesses.

Summary:

  • A retrospective study of 14 patients (1994-2004) revealed psoas abscesses are secondary, with common origins in gastrointestinal (7) and osteoarticular (6) systems.
  • Clinical manifestations included abdominal pain (64%), fever (57%), and back pain (43%).

  • Mycobacterium tuberculosis (5), Streptococcus intermedius (4), Staphylococcus aureus (3), Escherichia coli (3), and Bacteroides fragilis (2) were identified pathogens. Tuberculous abscesses, often from spondylitis, had a more insidious presentation.

    • Impact:

    • Computed tomography is the primary diagnostic tool.
    • Drainage (percutaneous or surgical) combined with a mean of 4 weeks of antimicrobial therapy led to complete resolution in all cases.
    • Highlights the significant proportion of tuberculous etiology and its distinct presentation, emphasizing the need for prolonged treatment.
