Abstract
Acute cerebellitis commonly presents as acute ataxia in children. Rarely, it can result in obstructive hydrocephalus. We report a 10-year-old boy with Mycoplasma infection-associated acute cerebellitis and obstructive hydrocephalus that responded well to conservative management with no residual neurological deficit. Wide recognition of this treatable clinical entity among neurologist would avert unnecessary investigations and ensure rationale management.
