Obstructive Hydrocephalus Caused by an Unruptured Arteriovenous Malformation Successfully Treated by Endoscopic Third Ventriculostomy After Shunt Dysfunction.

A ventriculoperitoneal (VP) shunt was inserted in emergency. Due to its large volume, the AVM was not referred for treatment and a follow-up policy was chosen.
