Optic glioma masquerading as spasmus nutans

S B Koenig, T P Naidich, Z Zaparackas

    Journal of Pediatric Ophthalmology and Strabismus
    |January 1, 1982
    PubMed
    Summary

    A rare pediatric brain tumor, juvenile pilocytic astrocytoma, can mimic spasmus nutans symptoms. This tumor caused obstructive hydrocephalus and vision loss in an infant.

    Area of Science:

    • Pediatric neuro-oncology
    • Ophthalmology
    • Neurology

    Background:

    • Spasmus nutans is a rare, usually benign, triad of nystagmus, head tilting, and torticollis in infants.
    • Optic pathway gliomas are tumors that grow along the optic nerves, chiasm, and tracts.

    Observation:

    • An eight-month-old infant presented with symptoms suggestive of spasmus nutans.
    • The infant later developed obstructive hydrocephalus, bilateral optic atrophy, and vision loss.

    Findings:

    • A juvenile pilocytic astrocytoma involving the optic nerves, chiasm, and anterior third ventricle was diagnosed.
    • The tumor's location and effects mimicked the clinical presentation of spasmus nutans.

    Implications:

    • Juvenile pilocytic astrocytomas in the optic pathway can present with signs that imitate spasmus nutans.
    • Early recognition and neuroimaging are crucial for differentiating these tumors from benign conditions.
