What is a choroid plexus tumor?

Choroid plexus tumors (CPTs) begin in the brain within areas called ventricles that are filled with cerebrospinal fluid. As CPTs grow, they block the flow of cerebrospinal fluid. This can increase pressure on the brain and cause the skull to get bigger.

A CPT may be noncancerous (benign) or cancerous:

How common are choroid plexus tumors?

Overall, choroid plexus tumors are rare and represent only about 3% of brain tumors in children.

They are most common in infants but can occur at any age. Choroid plexus tumors account for 10 to 20 percent of brain tumors diagnosed in children from birth to one year of age.

Choroid plexus papillomas (CPP) account for about 80% of all choroid plexus tumors.

Choroid plexus carcinomas (CPC) account for 10% to 20% of childhood choroid plexus tumors.

What are the symptoms of choroid plexus tumors?

CPT symptoms vary depending on the tumor’s location and size and the patient’s age. If your child has a CPT, symptoms may include the following:

An infant or toddler with CPT may have trouble feeding or walking. The child’s fontanel (the “soft spot” at the top of the skull) may also become fuller.
