Summary

Primary angiitis of the central nervous system (PACNS) in children presents in progressive and nonprogressive forms. Neurocognitive dysfunction, multifocal lesions, and distal stenoses predict progressive disease in pediatric PACNS patients.

Area of Science:

  • Neurology
  • Pediatric Neurology
  • Vascular Neurology

Background:

  • Primary angiitis of the central nervous system (PACNS) is a rare and poorly understood neurological condition.
  • Understanding its presentation and progression in children is crucial for effective management.

Purpose of the Study:

  • To characterize the clinical features, treatment, and outcomes of pediatric PACNS (cPACNS).
  • To identify predictors of disease progression in cPACNS to define high-risk patient groups.

Main Methods:

  • Retrospective analysis of 62 consecutive pediatric patients diagnosed with cPACNS.
  • Evaluation of clinical presentation, neuroimaging (conventional angiography, MR angiography), and cerebrospinal fluid findings.
  • Multivariate regression models used to identify predictors of angiographic disease progression at >3 months.

Main Results:

  • Two distinct subgroups emerged: progressive and nonprogressive cPACNS.
  • Progressive disease occurred in 20 of 62 children.
  • Predictors of progression included neurocognitive dysfunction, multifocal MR imaging lesions, and distal stenoses on angiography.

Conclusions:

  • Pediatric PACNS encompasses both progressive and nonprogressive disease forms.
  • Specific diagnostic features can predict disease progression in children.
  • Identification of high-risk cPACNS patients can guide immunosuppressive therapy selection.
