Choroid Plexus Tumor Defined

The choroid plexus is located within the ventricles of the brain and produces cerebral spinal fluid.  A choroid plexus tumor arises in this location of the brain. They account for approximately 1-3% of pediatric brain tumors and are most common in infants.

Types:

• Choroid plexus papilloma: a non-malignant form of a choroid plexus tumor which grows slowly within the ventricles.
• Choroid plexus carcinoma: a malignant form of the choroid plexus tumor which commonly grows in the lateral ventricles.

Symptoms:

• Hydrocephalus

Treatment:
Surgery is a common treatment option and if the tumor is malignant, chemotherapy and/or radiation therapy.
