Implication

Case highlights the potential of metagenomic next-generation sequencing in diagnosing encephalitis, suggesting links between human pegivirus and CNS pathology.

Key Points

Identification of human pegivirus as a possible cause of opsoclonus-myoclonus offers new diagnostic avenues.
IV immunoglobulin treatment resolved symptoms, suggesting immune-mediated central nervous system involvement.
Clinically validated mNGS provides significant diagnostic insight but faces technical and logistic hurdles.
Comprehensive testing initially ruled out multiple etiologies, emphasizing mNGS's unique utility.
