Melioidosis, caused by Pseudomonas pseudomallei, has a high mortality rate if untreated. Early detection through imaging analysis is crucial for timely intervention and improved patient outcomes.

Area of Science:

  • Infectious Diseases
  • Medical Imaging
  • Microbiology

Background:

  • Melioidosis is a severe infectious disease caused by Pseudomonas pseudomallei.
  • Prompt diagnosis is often delayed, leading to high mortality rates (80-100%) if untreated.
  • Understanding the clinical and imaging features is vital for early detection.

Purpose of the Study:

  • To analyze the imaging patterns of melioidosis patients.
  • To identify common presentations and associated risk factors.
  • To emphasize the importance of increased awareness for early diagnosis and treatment.

Main Methods:

  • Retrospective analysis of imaging patterns in 28 melioidosis patients over a 6-year period.
  • Correlation of clinical presentation with imaging findings.

  • Review of patient demographics and comorbidities.

    • Main Results:

    • Respiratory infections were the most common presentation, associated with the highest mortality.
    • Diffuse airspace consolidation was a frequent finding in respiratory melioidosis.
    • Visceral and musculoskeletal infections indicated chronicity and high relapse rates, with splenic abscesses and septic arthritis of the knee being common.
    • Diabetes mellitus and chronic ill-health were prevalent comorbidities.

    Conclusions:

    • Increased awareness of melioidosis imaging findings can facilitate earlier diagnosis.
    • Prompt and appropriate treatment is essential to reduce the high mortality associated with this infection.
    • Imaging plays a critical role in identifying diverse manifestations of melioidosis.
