Treatment of choroid plexus tumours

Choroid plexus papillomas

Choroid plexus papillomas are benign, slow-growing tumours. They are usually treated by surgery alone. These types of tumours often block the flow of cerebrospinal fluid (CSF), causing a buildup of CSF in the brain (hydrocephalus). Sometimes, removing the tumour will not relieve the fluid buildup and the surgeon may have to insert a shunt to allow the fluid to flow freely.

Choroid plexus carcinomas

Choroid plexus carcinomas are usually treated first by surgery. Chemotherapy and radiation therapy are typically given after surgery. Radiation may be delayed in children under the age of 3 years to avoid the effects of radiation on developing brain cells.

Recurrent choroid plexus carcinomas

A second surgery may be done on recurrent choroid plexus carcinomas. This may be followed by radiation therapy (if it was not given as an initial treatment) and chemotherapy.
