A 3.5-year-old male child patient with mild developmental delay presented with history of acute onset fever, encephalopathy, and dyskinesia. The patient was investigated for common etiologies and was managed supportively. His neuroimaging was suggestive of vanishing white matter (VWM) disease which was confirmed by clinical exome sequencing. The child had an eventful hospital stay followed by near-total recovery after 4 weeks. The case attempts to sensitize readers about the current perspectives pertaining to VWM disease.
