Insights

A rare polymicrobial brain abscess in a child with congenital cyanotic heart disease (CCHD) was successfully treated. Prompt cranial imaging is crucial for early diagnosis in at-risk pediatric patients with neurological changes.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Pediatrics

Background:

  • Brain abscesses are serious infections, but polymicrobial cases are uncommon in children.
  • Congenital cyanotic heart disease (CCHD) can increase the risk of brain abscesses.

Observation:

  • A 9-year-old girl with CCHD presented with right hemiplegia following an oropharyngeal injury.
  • Diagnosis was challenging due to nonspecific symptoms.

Findings:

  • The patient was diagnosed with a brain abscess caused by *Streptococcus intermedius*, *Parvimonas micra*, and *Fusobacterium nucleatum*.
  • Treatment included intravenous antibiotics, surgical drainage, and antiedema therapy.
  • Neurological deficits resolved, and the patient was discharged after eight weeks of therapy.

Implications:

  • This case underscores the importance of early cranial imaging in pediatric patients with CCHD and neurological symptoms.
  • Prompt diagnosis and treatment are vital for favorable outcomes in pediatric brain abscesses.
  • Highlights the potential for polymicrobial brain abscesses in children with specific risk factors.
