What are Colloid Cysts?

Colloid cysts are benign, fluid filled sacs that arise typically at the junction of lateral ventricles and the third ventricle, often causing obstructive hydrocephalus.

When symptomatic, these cysts should be removed surgically. This can be done endoscopically or with a keyhole minimally invasive craniotomy for more complex cysts. Generally, surgical resection alone can treat the hydrocephalus, minimizing the need for placement of a ventriculoperitoneal shunt.
