Diagnosis

A choroid plexus carcinoma most often occurs in children under 2 years old. Tests and procedures used to diagnose choroid plexus carcinoma include:

• Physical exam. Diagnosing a choroid plexus carcinoma usually starts with a medical history review and a neurological exam. During this procedure, your child's vision, hearing, balance, coordination and reflexes are tested.
• Brain imaging tests. Tests to create images of your brain may include magnetic resonance imaging (MRI) and computerized tomography (CT). An MRI also helps your doctor to plan the surgery.
• Genetic tests. Tests to identify genetic aspects of some choroid plexus carcinomas are available. Ask your doctor about genetic counseling.

Treatment in children usually differs from treatment in adults. If your child receives a diagnosis of choroid plexus carcinoma, ask your doctor to refer you to a specialist in treating children with brain tumors (pediatric neuro-oncologist, pediatric radiation oncologist).
