Balo concentric sclerosis in children: a case series

Area of Science:

• Neurology
• Immunology
• Pediatrics

Background:

• Baló concentric sclerosis (BCS) is a rare demyelinating disease.
• Pathologically, BCS is defined by alternating rings of demyelination and preserved myelin.
• Its prevalence, particularly in pediatric populations, remains largely unknown.

Observation:

• This study reports on 3 female pediatric patients with BCS-like demyelinating disease.
• These cases constituted 2.2% of 134 pediatric patients with demyelinating diseases evaluated since 2005.
• None of the reported pediatric cases were fatal.

Findings:

• The observed prevalence suggests BCS-like conditions may be more common in children than previously recognized.
• Pediatric cases of BCS-like disease exhibit a different clinical course compared to adults.
• The developing immune and central nervous systems may influence disease manifestation and response.

Implications:

• These findings challenge the traditional view of BCS as exclusively an acute, fatal adult disease.
• Understanding pediatric-specific demyelinating disease patterns is crucial for accurate diagnosis and treatment.
• Further research is warranted to explore the unique immunological and neurological factors in pediatric demyelinating disorders.
