Choroid plexus tumor

The first step in treating your child is forming an accurate and complete diagnosis, so your child’s physician may order a number of different tests. In addition to a physical exam, a medical history and neurological exam (which tests reflexes, muscle strength, eye and mouth movement, coordination and alertness), your child’s doctor may request tests including:

• computerized tomography scan (also called a CT or CAT scan) - a diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images of the brain. CT scans are more detailed than general x-rays. If a choroid plexus tumor is suspected, your child may have a CT scan of the brain.
   
• magnetic resonance imaging (MRI) - a diagnostic procedure that uses a combination of large magnets, radiofrequencies and a computer to produce detailed images of the brain and spine.
   
• biopsy - in many cases, a tissue sample from the tumor will be taken through a needle during a simple surgical procedure to confirm the diagnosis.
   
• lumbar puncture (spinal tap) - to remove a small sample of cerebrospinal fluid (CSF), a special needle is placed into the lower back, into the spinal canal, the area around the spinal cord. CSF is the fluid that bathes the brain and spinal cord. The sample is sent for testing to determine if any tumor cells have started to spread. For children, this procedure is safely performed under sedation, and is less difficult and less painful than placing an intravenous (IV) catheter. 

After we complete all necessary tests, our experts meet to review and discuss what they have learned about your child's condition. Then we will meet with you and your family to discuss the results and the best treatment options.
