title: Optic glioma masquerading as spasmus nutans.
abstract: An eight-month-old child who presented with signs of spasmus nutans subsequently developed obstructive hydrocephalus, bilateral optic atrophy, and loss of vision due to a juvenile pilocytic astrocytoma involving the optic nerves, chiasm, and anterior third ventricle. It appears that gliomas arising from this region may produce signs that imitate spasmus nutans.
