Suprasellar Cyst Presenting With Bobble-Head Doll Syndrome.

BACKGROUND: Bobble-head doll syndrome is a rare neurological syndrome presenting with repetitive anteroposterior head movements. It is usually associated with expansile cystic lesions in the third ventricular region. CASE DESCRIPTION: An 8-year-old boy presented with involuntary bobbling head movements. Magnetic resonance imaging of the brain revealed an extensive suprasellar cyst resulting in obstructive hydrocephalus. Endoscopic ventriculo-cysto-cisternostomy resulted in improved clinical outcome. CONCLUSIONS: Endoscopic ventriculo-cysto-cisternostomy is an effective, less-invasive technique in the treatment of suprasellar cysts that results in resolution of the bobbling head movements.
