Endoscopic Third Ventriculostomy and Aqueductal Stenosis

Abstract

A 15 years-old male patient presented with a progressive headache for the last six months, followed by diplopia and dizziness. Two months after he developed urinary incontinence. Neurological exam revealed an ataxic gait, horizontal nystagmus, and hyperreflexia in all members. Magnetic Resonance imaging suggest obstructive hydrocephalus with third and laterals ventricles dilatation, associated with aqueductual stenosis. The patient was submitted to endoscopic third ventriculostomy, where was observed an accentuated depression on tuber cinereum and Mammillary bodies, caused by the hydrocephalus chronicity. The procedure was done without complications and results in total reversion of ataxia and urinary incontinence.
