Insights

Pediatric spinal discitis (SD) is rare and often delayed in diagnosis. This case highlights an unusual *Klebsiella aerogenes* infection diagnosed via cell-free DNA, complicated by antibiotic resistance and abscess formation.

Area of Science:

  • Pediatric infectious diseases
  • Spinal infections
  • Microbiology

Background:

  • Spinal discitis (SD) is a rare pediatric condition with non-specific symptoms causing diagnostic delays.
  • Staphylococcus aureus is the most common pathogen; gram-negative infections are rarely reported.
  • Risk factors include comorbidities associated with bacteremia, such as diabetes, CKD, HIV, and cancer.

Observation:

  • An atypical case of SD in a previously healthy 15-year-old male is presented.
  • The causative organism identified was *Klebsiella aerogenes*, an unusual pathogen for SD.
  • Diagnosis was achieved using plasma microbial cell-free DNA testing, with negative blood cultures.

Findings:

  • The patient experienced antibiotic resistance, a common challenge in gram-negative infections.
  • A ventral epidural abscess developed, necessitating readmission and surgical intervention.
  • A prolonged course of antibiotics was required for treatment.

Implications:

  • This case expands the known spectrum of causative organisms in pediatric spinal discitis.
  • Plasma microbial cell-free DNA is a valuable diagnostic tool, especially when blood cultures are negative.
  • The management highlights the complexities of antibiotic resistance and surgical intervention in pediatric spinal infections.
