Choroid plexus carcinoma or choroid plexus tumor is a type of cancerous tumor that occurs in the brain’s choroid plexus tissue and most often occurs in children. The choroid plexus tissue lines the ventricles of the brain and produces cerebrospinal fluid or CSF. CSF circulates around the brain and spinal cord providing cushioning and protection. Because these tumors arise from the tissue involved in the making of CSF, the tumors can spread widely through this fluid. Symptoms of choroid plexus carcinoma are similar to those of other brain tumors including frequent headaches, unusually large head due to excess fluid on the brain, or large “soft spots” found on the baby's head. Other symptoms may include a decrease or loss of appetite and vomiting. The cause behind these tumors is largely unknown.
Treatment is usually surgical removal of the tumor and if removed completely, may be the only treatment necessary. If the recurs, a second surgery along with radiation and/or chemotherapy may be needed. Due to the nature of these tumors, it is critical to see a specialist on a regular basis for follow up and close monitoring. If your baby has been diagnosed with a choroid plexus carcinoma, talk to your baby's doctor and specialists about the most current treatment options. Additionally, there are support groups for people with brain tumors to assist you and your loved ones through this process.
