Pediatric Lumbar Puncture

During a lumbar puncture, your child's doctor on the Interventional Radiology team at Children's National Hospital will insert a needle into the lower spine:

  • To obtain cerebrospinal fluid (the fluid that circulates around the brain and spinal cord) to look for infection or cancer cells, or
  • To administer a chemotherapy agent for cancer patients, or
  • To monitor and relieve cerebrospinal fluid pressure for patients with pseudotumor
