CT Cisternography

If you have the following symptoms:

  • Fluid discharge from the nose
  • Positional headaches, which feel worse when sitting upright and better when lying down; caused by intracranial hypotension.
  • Contrast is required. It is recommended not to eat for at least 6 hours before the scan.
  • To determine the position of a possible CSF leak, a contrast material is injected into the subarachnoid space by lumbar puncture.
  • The patient is then tilted with the head down and a CT scan is performed to see where the CSF and the contrast is leaking out.
  • It is used to diagnose a CSF (cerebrospinal fluid) leak or identify blockages in the CSF pathways.
  • CSF is the fluid that is in the space that surrounds  the brain or spinal cord.
