Pediatric posterior fossa tumors often present subtly, but this case highlights an accelerated presentation of medulloblastoma with fever and altered mental status, leading to misdiagnosis.

Area of Science:

  • Pediatric oncology
  • Neuro-oncology
  • Pediatric neurology

Background:

  • Posterior fossa tumors are common in children, often presenting with insidious symptoms like headache and vomiting due to cerebrospinal fluid obstruction.
  • Typical signs include increased intracranial pressure, ataxia, cranial nerve palsies, and pyramidal tract signs.

Observation:

  • This case report details a pediatric medulloblastoma with an atypical, accelerated presentation.
  • The child presented abruptly with fever, nuchal rigidity, and altered mental status, mimicking meningitis.

Findings:

  • The accelerated presentation with minimal prodromal symptoms was not emphasized in previous literature on posterior fossa tumors.
  • This atypical presentation led to a misdiagnosis in the emergency department.

Implications:

  • Clinicians should consider rare, accelerated presentations of posterior fossa tumors even when symptoms mimic infection.
  • Early recognition and diagnosis of pediatric brain tumors are crucial for timely intervention and improved outcomes.
