Insights

Enteroviruses can cause transverse myelitis (TM) presenting atypically with ataxia in children. Prompt immunomodulatory therapy led to full recovery, suggesting an immune-mediated process.

Area of Science:

  • Neurology
  • Virology
  • Pediatrics

Background:

  • Enteroviruses, part of the Picornaviridae family, usually cause mild infections but can lead to central nervous system (CNS) disease.
  • Transverse myelitis (TM) is a rare but severe spinal cord inflammation causing neurological deficits.
  • Pediatric TM is uncommon, and its presentation can be atypical.

Purpose of the Study:

  • To describe a case series of pediatric patients with transverse myelitis (TM) presenting with ataxia.
  • To investigate the association between enterovirus infection and atypical TM presentation in children.
  • To evaluate the efficacy of immunomodulatory therapy in pediatric TM.

Main Methods:

  • Retrospective case series of eight pediatric patients admitted between June and August 2024.
  • Clinical assessment, cerebrospinal fluid (CSF) analysis, and magnetic resonance imaging (MRI) were performed.
  • Enteroviral RNA detection or isolation was conducted; epidemiological links were assessed.

Main Results:

  • Eight pediatric patients presented with ataxia and neurological symptoms during an enterovirus epidemic.
  • MRI revealed findings consistent with TM in all patients, despite ataxia being the primary symptom.
  • Enterovirus was detected in seven patients, with one having close contact; all patients recovered fully with immunomodulatory therapy.

Conclusions:

  • Ataxia can be an atypical presenting symptom of transverse myelitis (TM) in children.
  • A discrepancy between clinical presentation (ataxia) and neuroradiological findings (TM) was observed.
  • Immunomodulatory therapy (immunoglobulins, corticosteroids) is effective and safe, supporting immune-mediated pathogenesis in enterovirus-associated TM.
