Patients with colloid cysts develop blockage resulting in hydrocephalus of the two lateral ventricles. The ideal treatment is surgical resection of the colloid cyst in symptomatic patients.
There are multiple surgical approaches for resection of these cysts. The endoscopic intraventricular approach offers the advantages of a small bony opening, minimal disruption of the normal brain and good resection of the cyst and most of the cyst wall.
This approach has a slightly higher rate of cyst recurrence compared to other, larger openings. There is a small risk of requiring a ventriculoperitoneal shunt after this procedure.
