Tests and diagnosis
By Mayo Clinic staff
Eye exams
If pseudotumor cerebri is suspected, a doctor specializing in eye disorders will look for a distinctive type of swelling — called papilledema — in the back of your eye. You will also undergo a visual fields test to see if there are any blind spots in your vision.
Brain imaging
CT or MRI scans can rule out other problems that can cause similar symptoms, such as brain tumors and blood clots.
Spinal tap (lumbar puncture)
A lumbar puncture — which involves inserting a needle between two vertebrae in your lower back — can determine how high the pressure is inside your skull.
