Endoscopic third ventriculostomy for patients with hydrocephalus and fourth ventricular cysticercosis: a review of five cases.

The authors evaluate the feasibility of performing endoscopic third ventriculostomy (ETV) in a series of five patients with ventricular outlet obstruction and a prior history of fourth ventricular cysticercosis. All patients underwent fourth ventricular cyst excision and presented at various times afterwards with hydrocephalus. They were all successfully managed with ETV, and no patient has required subsequent surgery during a mean follow-up period of 21 months (range 12-36 months).
