====== Pineal Region Tumor Hydrocephalus ======

Patients presenting acutely due to [[hydrocephalus]] may be best treated with [[external ventricular
drainage]] (EVD). This permits control over the amount of CSF drained, prevents peritoneal seeding with tumor (a rare event

and may avoid having a permanent shunt placed in the significant number of patients who will not need one after tumor removal (although ≈ 90% of patients with a [[pineal germ cell tumor]] require a shunt). Ventricular access, via EVD or [[Frazier's point]] burr hole, in the post-op period is important in the event of acute hydrocephalus.
