Obstructive Hydrocephalus Induced Tremor in Patient with Mesencephalic Lacunae

ABSTRACT

We report a case of hydrocephalus in a 8-year-old boy who presented bilateral hand tremor. The hydrocephalus was caused by the aqueductal stenosis due to expanding lacunae in the mesencephalothalamic area on MR findings. The tremor was improved after CSF drainage by spinal tap and ventriculoperitoneal shunt. The authors present the possible mechanism of hydrocephalus induced tremor.
